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. but on a graph

Answer 1

Let's break down the costs involved in renting the scooter:

1. Hourly cost: $7.50 per hour.
2. Helmet rental: $3 per rental.

Since we are interested in finding the total cost in terms of the number of hours you rent the scooter, we can start by calculating the cost for the scooter usage and helmet rental separately.

Cost for scooter usage (per hour): $7.50 * x

The rental cost per hour ($7.50) is multiplied by the number of hours you rent the scooter (x).

Cost for helmet rental: $3

The helmet rental cost ($3) remains the same regardless of the number of hours you rent the scooter.

To get the total cost, we add the costs for scooter usage and helmet rental together:

Total cost = Cost for scooter usage + Cost for helmet rental
Total cost = $7.50x + $3

So, the algebraic expression that describes the total cost in terms of the hours you rent the scooter (x) is:
Total cost = $7.50x + $3

To graph this expression, you can plot the total cost ($ y-axis) against the number of hours you rent the scooter (x-axis), assuming a certain range or interval for x.
