The rental charge for a car is 34 cents for the 1st 1/4 mile driven and 6 cents for ever 1/5 mile driven over the initial 1/4 mile.

If a guy paid 1.24 in rental charge, how many miles did he drive?

2.50

3.00

3.25

3.75

4.00

Total Rent = Rent for the first 0.25 mile + Rent After 0.25 mile

Rent for the first 0.25 mile = 34 cents

Rent After 0.25 mile = [6 cent/(1/5 mile)]*(x - 0.25) = 30(x-0.25)

Therefore, Total Rent = 35 + 30(x - 0.25)

124 = 34 + 30(x - 0.25)

90 = 30(x - 0.25)

3 = x - 0.25

x = 3 + 0.25 = $3.25
