Homework 2.2 Part 2 (From worksheet)

1. A large pizza at Palanzio’s Pizzeria costs $6.80 plus $0.90 for each topping. The cost of a large pizza at Guido’s Pizza is $7.30 plus $0.65 for each topping. Which two equations represent each pizza place?

• C = 0.90t + 6.80

  C = 0.65t + 7.30

• C = 6.80t + 0.90

  C = 7.30t + 0.65

• C = 0.90t + 0.65t

  C = 6.80 + 7.30

1. A large pizza at Palanzio’s Pizzeria costs $6.80 plus $0.90 for each topping. The cost of a large pizza at Guido’s Pizza is $7.30 plus $0.65 for each topping. How many toppings need to be added to a large pizza from Palanzio’s Pizzeria and Guido’s Pizza in order for the pizzas to cost the same?

2. Some students want to order shirts with their school logo. One company charges $9.65 per shirt plus a setup fee of $43. Another company charges $8.40 per shirt plus a $58 fee. Which two equations represent each company?

• C = 9.65s + 43

  C = 8.40s + 58

• C = 43s + 9.65

  C = 58s + 8.40

• C = 9.65s + 8.40s

  C = 43 + 58

3. Mrs. Travis wants to have a clown deliver balloons to her secretary’s office. Clowns R Fun charges $1.25 per balloon and $9 delivery. Singing Balloons charges $1.95 per balloon and $2 for delivery. Write 2 separate equations that model each balloon company.

• C = 1.25b + 9

  C = 1.95b + 2

• C = 9b + 1.25

  C = 2b + 1.95

• C = 1.25b + 1.95b

  C = 9 + 2
