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.
HINT: Use the table to help you write the expression
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
The total cost in terms of hours, x, that you rent the scooter can be represented by the following algebraic expression:
Total cost = $7.50x + $3
To write the algebraic expression for the total cost of renting the scooter, we need to consider two components: the cost per hour and the cost for renting the helmet.
The cost per hour is given as $7.50, and this cost will be multiplied by the number of hours, represented by x.
The cost for renting the helmet is a fixed cost of $3, regardless of the number of hours.
Therefore, the algebraic expression for the total cost of renting the scooter in terms of hours, x, is:
Total Cost = (Cost per hour * Number of hours) + Cost for helmet
T(x) = (7.50 * x) + 3
Thus, the total cost can be calculated by multiplying $7.50 by the number of hours and then adding $3 for the helmet rental.
