Solving Inequalities: District 10

The dance committee of Pine Bluff Middle School earns $72 from a bake sale and will earn $4 for each ticket they sell to the Spring Fling dance. The dance will cost $400. Write an inequality to determine the number, t, of tickets the committee could sell to have money left over after they pay for this year's dance.

400<72 + 4t

The latest online craze is a new game, Khan on Seven. You get 100 points for playing the game. In addition, you get 50 points for each seven-letter word you make with the ten letters you receive. Sal wants to break the record, and he needs 18,000 or more points to do so. Write an inequality to determine the number of seven-letter words, w, Sal could make to break the record.

100 + 50w ≥ 18000

Use this inequality: 100 + 50w ≥ 18000. What number would your line graph begin at?

358

Renna pushes the elevator button, but the elevator does not move. The mass limit for the elevator is 450 kilograms but Renna and her load of identical packages mass a total of 620 kg. Each package has a mass of 37.4 kg. Write an inequality to determine the number of packages, p, Renna could remove from the elevator to meet the mass requirement.

450 ≥ 620 - 37.4p
