The Red Cross wants to airlift supplies into a South American country which has
experienced an earthquake. Four types of supplies, each of which would be shipped
in containers, are being considered. One container of a particular item weighs 120,
300, 250, and 500 pounds, respectively, for the four items. If the airplane to be used
has a weight capacity of 60,000 pounds and x j equals the number of containers
shipped of item j:
a) Determine the equation which ensures that the plane will be loaded to its
weight capacity.
b) If it is decided to devote this plane to one supply item only, how many
containers could be shipped of each item?

1. An elevator cab that weighs 27.8 kN moves upward. What is the tension in the cable if the cab’s speed is ___.
Find the mass of the elevator:
a. At rest
b. Uniform motion
c. Increasing at a rate of 1.2m/s2
d. Decreasing at the rate of 1.2m/s2
Please give me a solution and formula by letters. Thank you!
