Question

A taxi service charges a flat fee of $1.25 and $0.75 per mile. if henri has $14.00, which of the following shows the number of miles he can afford to ride in the taxi
a. m 17
b. m
c. m 20.3
d. m 20.3

Answer 1

Option m = 17

y = total cost of the service
m = number of miles run

y = 1.25 + 0.75 m

Equal the cost to the amount available by Henri

14 = 1.25 + 0.75m

Solve for m

m = (14 - 1.25)/0.75 = 12.75 / 0.75 = 17  miles.
