Question

Sam's surf shop rents surfboard for $20 per hour. In addition to the rental fee, there is a $5 service charge for every rental. Is the number of hours you can rent the surfboard proportional to the total cost? Fill in the table and explain your answer.

Answer 1

No the rental fee is not apart of the preposition you do $20x+5 because the rental fee is added to the entire rental, not every hour
