A car rental charges $25 a day plus.15 a mile for a compact car.Tess owes $61.40 for a two day rental. Which equation could be used to find the number of miles she drove.
we see that for m miles, the cost c is
c = 25 + .15m
(c-25)/.15 = m
so, m = (61.40-25)/.15
To find the equation that can be used to determine the number of miles Tess drove, let's break down the given information.
We know that the car rental charges $25 per day and an additional $0.15 per mile for a compact car. Tess owes $61.40 for a two-day rental.
Let's denote the number of miles Tess drove as 'm'.
For a two-day rental, the total cost consists of two components: the daily charge and the additional charge per mile.
The daily charge for a two-day rental would be 25 * 2 = $50.
The additional charge per mile would be 0.15 * m = 0.15m.
Therefore, the total cost for a two-day rental can be represented by the equation:
Total Cost = Daily Charge + Additional Charge per Mile
$61.40 = $50 + 0.15m
So, the equation that can be used to find the number of miles Tess drove is:
0.15m = $61.40 - $50
Simplifying the equation further:
0.15m = $11.40
