Solve the compound inequality and interpret the solution.

Question

Billy is helping to make pizzas for a school function. He's made 25 pizzas so far. His principal asked him to make at least 30 pizzas but no more than 75. Solve the compound inequality and interpret the solution.

30 ≤ x + 25 ≤ 75

Answer 1

30< x + 25 < 75

subtract 25 from each both sides and the middle

5 < x < 50

Billy needs to make between 5 and 50 more pizzas
