Question

Primo car rental agency charges $25 per day plus $0.30 per mile. Ultimo car rental agency charges $30 per day plus $0.95 per mile. Find the daily mileage for which the Ultimo charge is three times the Primo charge.

The mileage is

Answer 1

`28(4)/(7)` miles

Explanation:

mileage = m

Primo: cost = 0.3m + 20

Ultimo: cost = 0.95m + 30

Ultimo = twice Primo

0.95m + 30 = 0.6m + 40

subtract 0.60m and 30 from each side and simplify to get

0.35m = 10

divide by 0.35 into both sides to get

m =
`28(4)/(7)`

therefore, the daily mileage would be
`28(4)/(7)` miles
