Question

An airplane is loaded with cargo and ready to take off. Before it departs, an unknown number of 8-pound boxes, b, will be taken off the plane and a 600-pound crate will be put on. To keep the plane in balance, no more than 400 pounds may be taken off the plane. Write an inequality that best describes this situation.

A) b - 8 ≤ 400
B) b - 8 ≥ 400
C) b + 8 ≤ 400
D) b + 8 ≥ 400

Answer 1

The inequality that best describes the situation is b * 8 ≤ 400.

Step-by-step explanation:

To describe the situation, we can set up an inequality using the unknown number of 8-pound boxes, b. Since no more than 400 pounds can be taken off the plane, the inequality would be: b × 8 ≤ 400. This represents the condition that the total weight taken off the plane (which is the unknown number of boxes times 8 pounds) must be less than or equal to 400 pounds.
