Resource Management The average weights of the three species stocked in the lake referred to in Section 2.2, Exercise 59, are 1.62, 2.14, and 3.01 kg for species A, B. and C. respectively.
(a) If the largest amounts of food that can be supplied each day are as given in Exercise 59, how should the lake be stocked to maximize the weight of the fish supported by the Lake?
(b) Does it require all of the available food to produce the maximum weight of fish? If not, how much of each type of food is left over?
(c) Find a value for each of the average weights of the three species that would result in none of species B or C being stocked to maximize the weight of the fish supported by the lake, given the constraints in part (a).
(d) Find a value for each of the average weights of the three species that would result in none of species A or B being stocked to maximize the weight of the fish supported by the lake, given the constraints in part (a).

- Optimal Cost A public aquarium is adding coral nutrients to a large reef tank. The minimum amounts of nutrients A, B, and C that need to be added to the tank are 30 units, 16 units, and 24 units, respectively. Information about each bottle of brand X and brand Y additives is shown below. How many bottles of each brand must be added to satisfy the needs of the reef tank at the minimum possible cost?

There is room in the store to stock up to 60 computers. The manager receives a commission of 50 on the sale of each IBM-compatible computer and 40 on the sale of each Apple computer. If the manager can sell all of the computers, how many should she stock to maximize her commissions? Find the maximum commission.
