You're eqn will come up:
$Rental charge + ($Rate)(No. of miles driven) = $ Cost
Showing this in figures: , in dollars
$25+ ($x/mile)(no. of miles driven) = $Cost
$25 +($x/mile)(320 miles)= $89 ------------------> eqn 1

x=$0.20
There you go the rental car charge $0.20/mile driven plus $25 flat rate
In doubt? go back eqn 1:

Thank you,
