Lets write the expression for the cost of renting a full-size car.
FS = ($50.00)x + ($0.80)y
Now the expression for renting a compact car.
CC = ($30.00)x + ($0.50)y
The cost of renting the full-size car exceed the cost of renting the compact car can be found by: FS - CC
FF-CC = ($50.00)x + ($0.80)y - (($30.00)x + ($0.50)y) Simplifying this expression, we'll get:
($50.00 - $30.00)x + ($0.80 - $0.50)y or
($20.00)x + ($0.30)y
