A pizza shop charges $12 per pizza and a delivery fee of $4.

Which equation represents the cost, c, for any number of pizzas, p?

• c = 4p + 12

• c = 12p + 4

• c = 16p

• p = 12 + 4 + c

A car rental company charges $56 plus $0.30 per mile driven.

Write a linear function to model this situation.

• y = 56x + 0.30

• 56x + 0.30y = 86

• y = 0.30x + 56

• y = 56 - 0.30x

Speedy Boat Rental charges a $15 deposit fee plus $2 for each hour of use to rent a paddle boat.  Write an equation for C, the total cost, to rent the boat for h hours.

• h = 2C + 15

• C = 15h + 2

• h = 15C + 2

• C = 2h + 15

A man is climbing down from 100 feet high descending 30 feet per minute. Which function models his descent?

• y = 100 - 30x

• y = 100 + 30x

• y = 100x + 30

• y = 100x - 30
