Question 1071131

A car rental cost $90 a day for the first 270 miles, plus $0.20 for each additional mile. if Sonya rental cost was $128 for a one day rental, how many miles did she drive?
<pre>Cost equation: {{{C(m) = .2m + 36}}}, where:
C(m) = Cost of daily rental, based on "m" miles
   m = Amount of MILES driven for the day
Substituting 128 for C(m), we find that the total amount of miles driven on that day was: {{{highlight_green(460)}}}
