Example: Solving a Destination Wedding Budget Application with a Linear Inequality
To calculate the amount of work needed to afford a trip for an event like a destination wedding, apply the linear inequality word problem strategy. For example, Brenda needs to pay for nights at a hotel at $ per night, $ for airfare, and $ for food and entertainment. She has $ in savings and earns $ an hour babysitting.
Let be the number of babysitting hours. Translating the requirement that expenses must be less than or equal to total available funds yields:
Solving for :
Brenda must babysit at least hours to have enough money to pay for the trip.
