The school store sells pencils for $0.30 each, hats for $14.50 each, and binders for $3.20 each. Elena would like to buy 3 pencils, a hat, and 2 binders. She estimated that the cost will be less than $20.

1. Do you agree with her estimate? Explain your reasoning.

2. Estimate the number of pencils could she buy with $5. Explain or show your reasoning

Answers

Answer 1

1. No I do not agree with her estimate, because after adding up all of the cost of the things she wants to purchase, the cost will be over 20 dollars.

2. With 5 dollars she could buy 16 pencils. .30x16=4.80, so she could buy 16 pencils

A company produces fruity drinks that contain a percentage of real fruit juice. Drink A contains 25% real fruit juice and Drink B contains 20% real fruit juice. Company made 280 liters of fruity drinks with 61 liters of real fruit juice. Write a system of equations that could be used to determine the number of liters of Drink A made and the number of liters of Drink B made. Define the variables that you use to write the system.

Answers

Answer:

x = amount of real fruit juice used to make Drink A

y = amount of real fruit juice used to make Drink B

Step-by-step explanation:

Let

x = amount of real fruit juice used to make Drink A

y = amount of real fruit juice used to make Drink B

1. The company used 100.5 liters of real fruit juice, then

2. Drink A:

x = amount of real fruit juice used

percentage of real fruit juice

Then

5x = amount of drink A produced

Drink B:

y = amount of real fruit juice used

percentage of real fruit juice

Then

amount of drink B produced

The company makes 30 more liters of Drink A than liters of Drink B, so

The system of two equations i

Answer:

A = liters of drink A at 10% real fruit juice

B = liters of drink B at 30% real fruit juice

A + B = 360

0.1*A + .3*B = 78 liters

Step-by-step explanation:

A = liters of drink A at 10% real fruit juice

B = liters of drink B at 30% real fruit juice

A + B = 360

0.1*A + .3*B = 78 liters

Then you can solve.

A = 360 - B

36 - 0.1B + 0.3 B = 78

0.2B = 42

B = 210 liters

A = 150 liters

Evaluate the expression for d = 4, f = –3, and g = –12.

fg − d + f = ?

Answers

d= fgf+g-F

Step-by-step explanation:

F = fg f + g - d solve the equation for d

Solve for d means we need to get 'd' alone

To get 'd' alone we need to move all the remaining terms to the other side

F = fg f + g - d

First we subtract fgf on both sides

F - fg f = g - d

Now we subtract g on both sides

F - fg f - g = - d

now divide all the term by -1, so sign changes for all terms

-F + fgf +g = d

so d= fgf+g-F

The cost to rent a boat can be modeled by the equation C = 18h + 35 where C is the total cost in dollars and h is the number of hours in which the boat is rented.

What is the rate of change?

Answers

Answer:

Step-by-step explanation:

Slope, rate of change, unit rate, speed are synonyms

y = mx + b

Slope "m" is a rate of change.

~~~~~~~~~~

C = 18h + 35

m = 18

The rate of change from the given equation is 18 dollars per hour

Given :

The cost to rent a boat can be modeled by the equation C = 18h + 35

Where h is the number of hours and 'C' is the total cost

Rate of change represents the cost to rent a boat for one hour .

From the given equation , [tex]C=18h+35[/tex]

35 is the initial cost and 18 is the cost to rent a boat every hour

The rate of change is cost to rent a boat for one hour that is our slope.

Slope is 18

The rate of change is 18 dollars per hour
