Question

A car service charges $5 per mile plus a 7.25% sales tax. How much would it cost to ride for 15 miles?

a) $86.25
b) $81.25
c) $92.50
d) $87.50

Answer 1

To calculate the cost of the car service, multiply the number of miles by the per-mile cost, then calculate and add the sales tax. For 15 miles at $5 per mile plus 7.25% sales tax, the total is approximately $80.44, which does not match any of the given options.

Step-by-step explanation:

To calculate the cost of a 15-mile ride with a car service that charges $5 per mile plus a 7.25% sales tax, you would initially multiply the number of miles by the cost per mile to find the subtotal:

15 miles × $5/mile = $75

Next, find the amount of sales tax by converting the percentage to a decimal and then multiplying by the subtotal:

7.25% sales tax means 0.0725 when converted to a decimal.

So, $75 × 0.0725 = $5.4375

Add this to the subtotal to get the total cost:

$75 + $5.4375 ≈ $80.44

Since none of the provided options match this calculation, the student may need to recheck their options.
