Question

Zachary can spend no more than ​$98 per day to rent a car. A car rents for ​$42 per day plus ​$0.20 per mile. What is the maximum number of miles that he can drive the​ car?

Answer 1

$98 minutes the $42/day leaves you with $56. $56 divided by .20/mile is 280 miles.

Answer 2

Total Cost= $0.20x+$42.00
Total Cost= $98.00
$98.00=$0.20x+$42.00
Subtract $42.00 from each side of the equation
$56.00=$0.20x
Divide both sides by $0.20
x=280 miles

Zachary could drive a maximum of 280 miles per day that he rents the car.
