Answer: a. $55 + $20h
b. $175
Step-by-step explanation:
From the question, we are informed that a school rent a dunking booth for a carnival and that the company charges $55 to rent the booth plus $20 for each hour of rental.
a. Write an expression for the cost of renting the dunking booth for h hours.
This will be:
= $55 + $20h
b. Use your expression to find the cost of 6 hours.
The equation to solve this will be:
= $55 + $20h
= $55 + $20(6)
= $55 + $120
= $175
