| Fund A | 15,000 | 75,000 | (40,000) |
| Fund B | 45,000 | 50,000 | (80,000) |
| No Investment | 0 | 0 | 0 |
| Probabilities | 0.2 | 0.3 | 0.5 |

Each coffee table produced by Robert West Designers nets the firm a profit of $9. Each bookcase yields a $12 profit. West’s firm is small and its resources limited. During any given production period, 10 gallons of varnish and 12 lengths of high-quality redwood are available. Each coffee table requires approximately 1 gallon of varnish and 1 length of redwood. Each bookcase takes 1 gallon of varnish and 2 lengths of wood.
Formulate West’s production-mix decision as a linear programming problem, and solve. How many tables and bookcases should be produced each week? What will the maximum profit be?
Use:
x = number of coffee tables to be produced
y = number of bookcases to be produced
Which objective function best represents the problem?
a. P= X + Y
b. P= 10 X + 12 Y
c. P= X + 2 Y
d. P= 9 X + 12 Y
