Explanation:
I guess, the question is, how many miles were driven ?
if that is the case, then
we need to deduct the basic fee of $14.75, as this would have been paid, even if they did not drive a single mile.
so, 50.45 - 14.75 = $35.70
that is the actual cost for the driven miles.
how many miles ?
well, how often do $0.15 fit into $35.70 ?
35.7 / 0.15 = 238 miles.
this customer had been driving the moving van for 238 miles.
