A car rental agency charges $140 a week plus $0.20 for each mile traveled over 125 miles. Sally has a total of $350 to rent a car for the week. How many miles can she drive?

Answer 1

$140 + 20 cents for each mile driven over 120 miles

how many miles can she afford with $350?

$140 gets her 120 miles

then she has 350-140 = $210 left for mileage

210 = .2(m)

m = 1050 miles

1050+120 = 1,170 miles possible on $350

m = 120 + (350-140)/.2

m = 120 +210/.2

m = 120+1050

m =1,170 miles maximum
