Question

A small plane's maximum takeoff weight is 2200 pounds or less Six passengers weigh an average of 160 pounds each Use an inequality to find the luggage and cargo weights the plane can carry The luggage and cargo must weight pounds or less

Answer 1

If one passenger weighs 160 pounds, then 6 passengers weigh 6*160 = 960 pounds

passengers weight + luggage and cargo weights = total weight

The total weight must be 2200 pounds or less. Calling x to the luggage and cargo weights, we get:

960 + x ≤ 2200

x ≤ 2200 - 960

x ≤ 1240

The luggage and cargo must weigh 1240 pounds or less​
