Example: Solving a Road Trip Budget Application with a Linear Inequality
To find the number of jobs required to fund a multi-night road trip, apply the linear inequality problem-solving strategy. For instance, Josue's -night trip will cost $ for gas, $ for food, and $ per night for a motel room. He has $ in savings and earns $ per driveway shoveling snow.
Let represent the number of driveways. The total trip cost must be less than or equal to his savings plus his total earnings:
Solving for :
Josue must shovel at least driveways to have enough money to pay for the trip.
