Question

A skydiving company insists that its customers weigh at least 130 pounds, but no more than 280 pounds, including parachute and other gear. If the total weight of all gear is 25 pounds, write and solve a compound inequality that represents the weight range without gear that is acceptable.

Answer 1

105 ≤ x ≤ 255

Explanation:

Given that :

Let weight range = x

130 ≤ x ≤ 280

Total weigh of gear = 25 pounds

The weight range without gear that is acceptable :

130 - weight of gear ≤ x ≤ 280 - weight of gear

130 - 25 ≤ x ≤ 280 - 25

105 ≤ x ≤ 255
