7) P=17.59x-2655 is the profit formula for x boxes of frozen pizza dough. (By the way, what is profit?)

Sedaia [141]

Answer:

Part A)

For 10 boxes $P=-\$2,479.10$

For 40 boxes $P=-\$1,951.40$

For 25 boxes $P=-\$2,215.25$

Part B) The number of boxes must be greater than or equal to 191 for a profit of at least $700

Part C) 151 boxes are needed to break even

Step-by-step explanation:

we know that

Profit, is equals to revenue minus costs of goods sold

we have

$P=17.59x-2,655$

Part A) Find the profit for

1) 10 boxes

For x=10 boxes

substitute in the formula

$P=17.59(10)-2,655$

$P=-\$2,479.10$

The negative means that the revenue is less than the costs

2) 40 boxes

For x=40 boxes

substitute in the formula

$P=17.59(40)-2,655$

$P=-\$1,951.40$

The negative means that the revenue is less than the costs

3) 40 boxes

For x=25 boxes

substitute in the formula

$P=17.59(25)-2,655$

$P=-\$2,215.25$

The negative means that the revenue is less than the costs

Part B) How many boxes needed for a profit of at least $700?

For P=$700

substitute in the formula and solve for x

$700=17.59x-2,655$

$17.59x=2,655+700$

$17.59x=3,355$

$x=190.7\ boxes$

Round up

$x=191\ boxes$

therefore

The number of boxes must be greater than or equal to 191 for a profit of at least $700

Part C) How many boxes needed to “break even”?

we know that

Break even is when the profit is equal to zero

For P=0

$0=17.59x-2,655$

$17.59x=2,655$

$x=150.9$

Round up

151 boxes are needed to break even

A cashier has 30 bills, all of which are $10 or $20 bills. The total value of the money is $460. How many of each type of bill d

Andru [333]

Answer:

$10 bill = 14 and $20 bill = 16.

Step-by-step explanation:

Given : A cashier has 30 bills, all of which are $10 or $20 bills. The total value of the money is $460.

To find : How many of each type of bill does the cashier have.

Solution : We have given that

A cashier has 30 bills

Let bill of $10 = x .

Bill of $20 = y .

Money of $10 = 10x .

Money of $20 = 20y.

Total bill

x + y = 30-------(1)

10x + 20y = 460-----(2)

On multiplying equation 1 by 10 and subtracting from equation 2.

10x + 20 y = 460

(-)10x +(-) 10 y = (-)300

______________

0 + 10 y = 160 .

On dividing by 10

y = 16 .

Plug y = 16 in equation 1

x + 16 = 30

On subtracting both sides by 16.

x = 30 - 16.

x = 14

Therefore, $10 bill = 14 and $20 bill = 16.

Alicia is making cupcakes for a party she is having and wants to make sure everyone gets at least one cupcake. The recipe calls

Liula [17]

$\frac{84}{21}=4$

Therefore you need 4 batches of cupcakes if you want every person to get one cupcake.

This means you multiply the amount of salt per batch by the number of batches, to get the total amount of salt you need.
Each batch contains 1 teaspoon of salt for 21 cupcakes. Multiply: $4\text{ batches of cupcakes}\times1\text{ teaspoon of salt}=4\text{ teaspoons salt}$ for the whole thing.
