There is a daily fee for renting a moving truck, plus a charge of $0.50 per mile driven. If driven 48 miles, it costs $64 to rent a truck. Write and solve and equation to find the daily fee.

Question

Luigi0210 · Answer

So we have the equation $ ax+b =c $ where

a - charge per mile 
x - miles driven
b - daily fee
c - total cost

Plugging everything in you get: $0.50x + b = 64 $
It is given that they drove 48 miles, so you can plug that in as well and solve:

$0.50(48)+b = 64 $ 
$ 24+b = 64$

And you get b as $ b= 40 $

So the daily fee for renting the moving truck is $\color{gold}{$40}$ (Assuming this is just a one-day use).
