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 50 pounds, and earns $13 for the driver. Each crate of cargo B is 3 cubic feet in volume, weighs 250 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 to twice the number o crates of cargo A A cubic feet pounds S B cubic feet pounds S Truck capacity Volume Weight 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. cubic feet pounds $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 (d) Express the earnings from carrying x crates of cargo A and y crates of cargo B. Earnings is
