You want to deliver a package to Japan. The FedEx delivery service charges a $10 flat fee plus $2 per pound. You can also use the USPS Priority Mail service which charges a $2 flat fee plus $4 per pound.

Write an equation for the cost for USPS Priority Mail to send the package.
Use x as the number of pounds and use y as the total cost.

Answers

Answer 1

Answer:5kg

Step-by-step explanation:

Step 1.

Write in y=mx+c format

m= $/kg

c=flat fee

x=additional kilograms

FedEx:

y=2x+15

USPS:

y=5x

Step 2.

Keep Changing the x value (the no. of kilograms) in both equations until y is the same number

y=5×5

=25

y=2×5+15

=25

∴It would cost the same for both options at 5kg

Total Surplus The sum of consumer surplus and producer surplus is called the total surplus; it is one measure economists use as an indicator of the economic health of a society. Total surplus is maximized when the market for a good is in equilibrium. A camera company estimates that the demand function for its new digital camera is and the supply function is estimated to be here is measured in thousands. Compute the maximum total surplus.

Answers

The total surplus at the equilibrium point is: $200,000

This is the maximum total surplus that can be achieved in the market for the digital camera.

To compute the maximum total surplus, we need to find the equilibrium quantity and price in the market for the digital camera, and then calculate the consumer and producer surplus at that point.

First, we need to set the demand and supply functions equal to each other to find the equilibrium quantity:

50 - 2P = 2P - 10

4P = 60

P = 15

Substituting this equilibrium price into either the demand or supply function, we can find the equilibrium quantity:

Q = 50 - 2(15) = 20

So the equilibrium price is $15, and the equilibrium quantity is 20,000 digital cameras.

Next, we can calculate the consumer and producer surplus at the equilibrium point. Consumer surplus is the difference between the maximum price a consumer is willing to pay for a good and the market price, summed over all consumers in the market. Producer surplus is the difference between the market price and the minimum price a producer is willing to accept for a good, summed over all producers in the market.

The demand function gives us the maximum price consumers are willing to pay for each quantity of digital cameras:

P = 25 - 0.5Q

So at the equilibrium quantity of 20,000 digital cameras, the maximum price consumers are willing to pay is:

P = 25 - 0.5(20) = 15

This is exactly the same as the market price, so there is no consumer surplus at the equilibrium point.

The supply function gives us the minimum price producers are willing to accept for each quantity of digital cameras:

P = 0.5Q - 5

So at the equilibrium quantity of 20,000 digital cameras, the minimum price producers are willing to accept is:

P = 0.5(20) - 5 = 5

The market price is $15, so the producer surplus is:

(15 - 5) * 20 = $200,000

Therefore, the total surplus at the equilibrium point is:

$200,000

This is the maximum total surplus that can be achieved in the market for the digital camera.

We know that 2.5 kg of onions and 2 kg of carrots cost £2.36.

The cost of 15 2.5 kg of onions is 15 × 2.5 = 37.5 kg of onions.

The cost of 1 kg of onions is 2.36 ÷ 37.5 = 0.06293 = £0.063.

3 kg of carrots cost £1.74. and we need to find how much 1kg of carrots cost.

Therefore, the cost of 1 kg of carrots is 1.74 ÷ 3 = 0.58 = £0.58.

Now we can use the above information to find the cost of 4 kg of onions:

The cost of 1 kg of onions is £0.063.

Hence, the cost of 4 kg of onions is 4 × 0.063 = £0.252.

2 A customer applied for a loan for $15,000 to buy a motorcycle. The customer qualified for different loan options. Which loan option would allow the customer to pay the least amount of interest? (A A 3-year loan with an 7% annual simple interest rate B A 4-year loan with a 5% annual simple interest rate CA 5-year loan with a 4.5% annual simple interest rate A 6-year loan with a 3.7% annual simple interest rate​

Answers

From the calculations, the best loan option is

A. 3-year loan with a 7% annual simple interest rate

How to find a better loan option

To determine which loan option would allow the customer to pay the least amount of interest, we need to compare the amount of interest charged by each loan option.

For the 3-year loan with a 7% annual simple interest rate,

the interest charged would be $15,000 x 7% x 3 = $2,550.

For the 4-year loan with a 5% annual simple interest rate,

the interest charged would be $15,000 x 5% x 4 = $3,000.

For the 5-year loan with a 4.5% annual simple interest rate,

the interest charged would be $15,000 x 4.5% x 5 = $3,375.

For the 6-year loan with a 3.7% annual simple interest rate,

the interest charged would be $15,000 x 3.7% x 6 = $3,870.

From the calculations, it is clear that the 3-year loan with a 7% annual simple interest rate would result in the least amount of interest charged, with $2,550.

2/10 Net 30:

The terms and conditions of the transaction are set forth in the purchase order and the corresponding invoice. These terms include terms of credit between the seller (also known as the payee) and the buyer (also known as the payer). A typical net credit period of 30 means the balance must be paid within 30 days of the invoice date. 2/10 Net 30 (also known as 2 10 Net 30) means that if a buyer pays within the first 10 days, their balance will be reduced by 2%. So "2" is the discount amount (2%) and "10" is the due date (10 days).

For example, if your company purchased $500 worth of goods or services on June 1st, you have entered into a loan agreement with the seller. If your company pays the net amount between June 1st and June 10th, you get a 2% discount, bringing the total amount to $490.

the slope of the perpendicular bisector is 2

By point slope form

y - (-3) = 2(x - 7)

y = 2x - 17

And the equation of the perpendicular bisector of AC is:

y - (-2.5) = -1/2(x - 4.5)

y = -1/2x + 5

Now 2x - 17 = -1/2x + 2.25

2.5x = 19.25

x = 7.7

Substituting x = 7.7 into the equation for the perpendicular bisector of AB, we get:

y = 2(7.7) - 17

y = -6.6

Hence, coordinates of the circumcenter are (7.7, -6.6)

A player hits the bullseye with a dart 8% of the time. Based on this relative frequency, how many times can the bullseye be expected to be hit when the player throws the dart 40 times. WRONG ANSWER = BLOCKED

Answers

The probability of hitting the bullseye if the dart is thrown 40 times is approx. 3 times.

What is relative frequency?

The quantity of occurrences of an event is referred to as its frequency. The concept of relative frequency is experimental rather than theoretical. It is experimental, therefore if we repeat the trials, we can get different relative frequencies. To determine the frequency, we must first:

Number of occurrences for the entire population

Frequency count for a particular demographic segment

If we know the two frequencies mentioned above, we can use the following formula to get the relative frequency probability. A subgroup's formula is as follows:

Subgroup Count / Overall Count: Relative Frequency

Given that, a player hits the bullseye with a dart 8% of the time.

The probability of hitting the dart is = 8/100.

Now, the probability of hitting the bullseye if the dart is thrown 40 times is:

p = 40 (8/100) = 3.2 times = 3 times.

Hence, the probability of hitting the bullseye if the dart is thrown 40 times is approx. 3 times.

What is an Equation of a line?

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation of line be represented as A

Now , the value of A is
