While on vacation, you rent a scooter. You pay $7.50 for each hour you use it. It costs $3 to rent a helmet. Write an algebraic expression that describes the total cost in terms of hours, x, that you rent the scooter.

Question

HINT: Use the table to help you write the expression

Answer 1

The cost of renting the scooter per hour is $7.50, so the algebraic expression for the total cost in terms of hours, x, is:

Total Cost = (Cost per hour x Number of hours) + Helmet cost

The helmet cost is a constant value of $3, so the algebraic expression becomes:

Total Cost = ($7.50x) + $3
