Planning for a concession stand
The athletic boosters for a local college raise money by selling popcorn at a concession stand. They charge customers $2.25 per box. The popcorn machine and supplies (unpopped kernels, popping oil and butter) are provided by a company that chargers a fee of $250 per game plus $0.15 per box of popcorn sold.
Task description:
What is the least number of boxes of popcorn that the athletic booster can sell at the next game to make a profit?
As you complete the task, you'll apply several Standards for Mathematical Practice:
- You will use an inequality that models the number of additional empty popcorn boxes needed for the next game
- You will manipulate symbols that represent quantities to solve an inequality
