A truck traveling from New York to Baltimore is to be loaded with two types of cargo. Each crate of cargo A is 5 cubic feet in volume, weighs 100 pounds, and earns $12 for the driver. Each crate of cargo B is 2 cubic feet in volume, weighs 200 pounds, and earns $8 for the driver. The truck can carry no more than 300 cubic feet of crates and no more than 10,000 pounds. Also, the number of crates of cargo B must be less than or equal twice the number of crates of cargo A. (a) Fill in the chart. A cubic feet pounds S Truck capacity B cubic feet Volume Weight pounds $ Earnings (b) Let x be the number of crates of cargo A and y the number of crates of cargo B. Referring to the chart, give the two inequalities that x and y must satisfy because of the truck's capacity for volume and weight. $300 ≤ 10,000 (c) Give the inequalities that x and y must satisfy because of the last sentence of the problem and also because x and y cannot be negative. ys y² x² cubic feet pounds (d) Express the earnings from carrying x crates of cargo A and y crates of cargo B. Earnings is
