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 33 nights at a hotel at $6060 per night, $350350 for airfare, and $375375 for food and entertainment. She has $500500 in savings and earns $1515 an hour babysitting.

Let hh be the number of babysitting hours. Translating the requirement that expenses must be less than or equal to total available funds yields: 350+375+60(3)500+15h350 + 375 + 60(3) \leq 500 + 15h

Solving for hh: 350+375+180500+15h350 + 375 + 180 \leq 500 + 15h 905500+15h905 \leq 500 + 15h 40515h405 \leq 15h 27h27 \leq h h27h \geq 27

Brenda must babysit at least 2727 hours to have enough money to pay for the trip.
