Alfred and Larissa have $21.00 each to spend at a book fair, where all students receive a 35% discount. They both want to purchase a copy of the same book, which normally sells for $28.50 plus 10% sales tax. To check if he has enough to purchase the book, Alfred takes 35% of $28.50 and subtracts that amount from the normal price. He takes 10% of the discounted selling price and adds it back to find the purchase amount. Larissa takes 65% of the normal purchase price and then computes 110% of the reduced price. Is Alfred correct? Is Larissa correct? Do they have enough money to purchase the book? Explain your answer using complete sentences and show your work.
Answer: See explanation
Step-by-step explanation:
The normal cost of the book plus the sales tax will be:
= $28.50 + ($28.50 × 10%)
= $28.50 + ($28.50 × 0.1)
= $28.50 + $2.85
= $31.35
Since there's a discount of 35%, the amount they'll have to pay will be:
= $31.35 - ($31.35 × 35%)
= $31.35 - ($31.35 × 0.35)
= $31.35 - $10.9725
= $20.3775
They do not have enough money to make the purchase.
Alfred takes 35% of $28.50 and subtracts that amount from the normal price. Alfred's calculation is shown below:
= $28.50 - (35% of $28.50)
= $28.50 - (0.35 × $28.50)
= $28.50 - $9.975
= $18.525
He takes 10% of the discounted selling price and adds it back to find the purchase amount. This will be:
= $18.525 + (10% × $18.525)
= $18.525 + $1.8525
= $20.3775
Alfred is correct
Larissa takes 65% of the normal purchase price and then computes 110% of the reduced price. This will be:
= 65% × $28.50
= 0.65 × $28.50
= $18.525
= 110% × $18.525
= 1.1 × $18.525
= $20.3775
Larisa is also correct

What is the base area.
Answer:
Area of the base is 10.5 cm².
Step-by-step explanation:
Formula for the volume of the given oblique prism = Area of the triangular base × Vertical height between two triangular bases
Vertical height = 6 cm
Volume = 63 cm³
From the formula,
63 = Area of the triangular base × 6
Area of the base = [tex]\frac{63}{6}[/tex]
= 10.5 cm²
Therefore, area of the base is 10.5 cm².

Jorge has a Total of 67 coins. All of which are dimes and nickels. The total value of the dimes and nickels i $5.40. Find the number of each type of coin.
Answer:
There are 41 dimes and 26 nickels.
Step-by-step explanation:
From the information given, you know that you have 67 coins which would be:
x+y=67
Also, you now that the value of each coin is:
dimes= $0.10
nickels=$0.05
With this you can say that the number of dimes for its value plus the number of nickels for its value is equal to $5.40:
0.10x+0.05y=5.40
You will have the following equations:
x+y=67 (1)
0.10x+0.05y=5.40 (2), where:
x are the number of dimes
y are the number of nickels
First, you can solve for x in (1):
x=67-y
Then, you can replace (3) in (2):
0.10(67-y)+0.05y=5.40
6.7-0.10y+0.05y=5.40
1.3=0.05y
y=1.3/0.05
y=26
Now, you can replace the value of y in (3) to find x:
x=67-y
x=67-26
x=41
According to this, the answer is that there are 41 dimes and 26 nickels.

Step-by-step explanation:
A: X=4
Step 1: Distribute the 7 within the parenthesis which will give you:
7x - 21 = 7
Step 2: Add over the -21 to the other side of the = which will give you:
7x = 28
Step 3: Divide by 7 on both sides to get the final answer, X=4
B: M=9
Step 1: Multiply by 4 on both sides, to cancel it out on the right, which will give you:
32 = 3m + 5
Step 2: Subtract the 5 from each side, giving you:
27 = 3m
Step 3: Divide by 3 on both sides to get the final answer, M=9
C: X=28
Step 1: Subtract 9 from both sides, giving you:
x/2 = 14
Step 2: Multiply by 2 on both sides to give you:
x = 28 (This will be our final answer, there is nothing left to simplify.)
D: X=3
Step 1: Distribute the 2 on the left and the (-) on the right to give you:
5 + 2x + 10 = 10 - 4 + 5x
Step 2: Combine like terms and simplify to give you:
15 + 2x = 6 + 5x
Step 3: Subtract over the (2x) to give you:
15 = 6 + 3x
Step 4: Subtract over the 6 to give you:
9 = 3x
Step 5: Divide by 3 on both sides to get the final answer, X=3

[tex]\huge\boxed{\sf Star = 14}[/tex]
Step-by-step explanation:
Let snowman be x , star be y and shopping bag be z.
So, the given equations are:
1) x + y = 20 (Eq. 1)
2) z = x + x
z = 2x (Eq. 2)
3) z + x = 18 (Eq. 3)
Put Eq. (2) in Eq. (3)
2x + x = 18
3x = 18
Divide both sides by 3
x = 18 / 3
x = snowman = 6
Now, Put x in (Eq. 1)
6 + y = 20
Subtract 6 to both sides
y = 20 - 6
y = 14
So,
Star = 14

Volume of a Cylinder: V = πr²hStep-by-step explanation:
Step 1: Define
Radius r = 3 in
Height h = 8 in
Step 2: Find Volume V
Substitute [VC]: V = π(3 in)²(8 in)Exponents: V = π(9 in²)(8 in)Multiply: V = 72π in³Multiply: V = 226.195 in³Step 3: Find Water
2/3 of vase should be filled with H₂O.
Set up: 2/3(72π in³)Multiply: 48π in³Evaluate: 150.796 in³Answer:
We know the formula for the volume of a cylinder is V=πr^2has given.
That said, we can plug our values in.
V=π3^2(8)
Simplify.
V=π9*8
V=72π
It needs 72π cubic inches of water.
This is also equivalent to around 226.19 cubic inches of water.

Length of a rectangle swimming pool is 50 yards and the width of the pool is 60 yards what is the approximate length of the diagonal of pool
Answer:
Approximately 78 yards
Step-by-step explanation:
From the question, I was able to deduce that the swimming pool is a cuboid because the length and width step different in yards. After sketching a cuboid, length= 60 yards, width= 50 yards, then draw a diagonal across the upper rectangle of the cuboid, to get the diagonal, use Pythagoras theorem, Hypotenuse²= opposite²+adjacent²;. x²=60²+50²=3600+2500=6100 ;.
x²=6100 therefore X=√6100 =78.1024 yards, but approximately 78yards, since the question instructed that answer should be approximated.

The y-intercept of the function y=−2x+8 is
Choose... greater than less than or equal to
the y-intercept of the function represented in the graph.
Answer:
equal to
Step-by-step explanation:
The y intercept is when x = 0.
In the function y=-2x+8, when x=0, y=8.
In the graph, when x=0, y=8. You can see on the x axis 0 is in the middle, and if you move up the y axis, you see the line intersects y=8.
Thus both have the same y intercepts of 8.

Martin is seating people in the cars of a roller coaster. Each car can seat 8 people. Six of the roller coaster cars are yellow and nine of the roller coaster cars are green. People will be randomly seated in the roller coaster cars. What is the probability that the first person will be seated in a yellow roller coaster car?
Answer:
The probability is 2/5
Step-by-step explanation:
Here, we want to calculate the probability that the first person will sit in a yellow roller coaster car
The number of cars to select from is 6 + 9 = 15 cars
The number of yellow cars is 6
So the probability that the first person selects a yellow roller coaster car to seat is 6/15 = 2/5

Answer:
x=14
Step-by-step explanation:
Solving the equation x - 10 = 4, the value of x, which is the solution is calculated as x = 14.
How to Solve an Equation?Solving an equation simply involves determining the value of the variable in the equation, which is the unknown.
For example, we are asked to solve the equation, x - 10 = 4., what it simply means is that we need to determine what the value of x is in the equation that will make it true. Do the following:
x - 10 = 4
x - 10 + 10 = 4+ 10 [addition property of equality]
x = 14
Therefore, the solution of the equation is x = 14.
