Assignment: Solve Inequalities with Multiplication and Division

Choose any three (3) of the following five problems to solve.

1. Players from the local Little League plans to hold a car wash as a fundraiser. If they charge

$5 per car, how many cars do they need to wash to earn at least $250 dollars?

a. Write an inequality to represent this situation, using x to represent the number of cars the players need to wash.

5x ≥ 250

b. Solve the inequality by isolating the variable. Show all work leading to your answer.

5x ≥ 250 x ≥ (250/5) x ≥ 50

c.

Graph the solution on the number line. Be sure to include number labels to show the values of x on the number line.

50--------------->100 ( closed circle)

d. Write 1-2 sentences to explain what
