Problema Solution
a taxi service charges an initial fee plus $1.80 per mile. How far can you travel for $12.00?
Answer provided by our tutors
let
'x' represent the number of miles u van travel with $12.00
'f' represents the initial fee
1.80x + f = 12.00
x = (12.00 - f)/1.80
u can travel (12.00 - f)/1.80 miles with $12.00.
if the initial fee f = 0 you can travel: x = 12/1.8 = 6.67 miles.
