Represent Given Situations Using Tables, Equations, Graphs

A driving range charges $4 to rent a golf club plus $2.75 for every bucket of golf balls you hit. Write an equation that shows the total cost c of hitting b buckets of golf balls.

• c = 2.75b + 4

• c = 2.75b

• c =  4b- 2.75

• c = 2.75b - 4

You earn $18 for every hour you work. Which equation represents this function?

• y=(18/2)x + 0

• y = 18x

• y = 2x + 18

• y = 18x + 2
