Answer:
Step-by-step explanation:
$57.50
Represent the total cost by R(m) = F + cm, where R is the total, F is the upfront (fixed) fee, and m is the number of miles the truck is driven.
In this case, R(m) = $45.00 + ($0.50/mile)m
If you drive 25 miles, m = 25, and R(25) = $45.00 + ($0.50/mile)(25 miles), or
R(25) = $45.00 + $12.50 = $57.50
