A booster club paid for pizzas for an end of season party. They paid $13 for each pepperoni pizza and $11 for each plain pizza. The club bought a total of 18 pizzas for the party and paid a total of $212. Drag and drop the numbers to the boxes to create an equation which models this situation if x = the number of pepperoni pizzas and y = the number of plain pizzas bought.

13x + 11y = 212

Step-by-step explanation:

total cost of purchasing an item = unit cost x total units purchased

total cost of purchasing pepperoni pizza = 13 × x = 13x

total cost of purchasing plain pizza = 11 × y = 11y

total cost of purchasing both items = total cost of purchasing pepperoni pizza + total cost of purchasing plain pizza

- 13x + 11y = 212

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
