Question 253430: Karen rented a car for the weekend in order to take her grandmother to visit relatives. the charge was a fixed rate of $15.00 plus $0.35 per mile. Karen wants to spend no more that 125.00 to rent the car?
Answer by Theo(13342) (Show Source): You can put this solution on YOUR website!
cost to rent the car is 15.00 plus .35 per mile.

if she can only spend 125, then:

125 = 15 + x * .35 where x is the number of miles she can drive.

subtract 15 from both sides of this equation to get:

125-15 = x*.35 which becomes:

110 = x*.35

divide both sides of this equation by .35 to get:

110/.35 = x which becomes:

314.2857143 = x

she can drive a maximum of 314.2857143 miles given her budget limitations.
