Question by Troy R: can you solve this linear programing problem?
A man raises chickens, ducks and turkeys. He has room for only 200 birds and wishes to limit the number of turkeys to a maximum of P25, the number of turkeys and ducks to a maximum of P 100. His estimated profits are P30, P25, and P 120 on each chicken, duck, and turkey respectively. How many of each should he raise to maximize his profit?

Let x1, x2, x3 are numbers of chickens, ducks and turkeys respectively. Then we”ll have the following problem:
Profit = 30*x1 +25*x2 + 120*x3 – to be maximized;
Constraints:
x1 + x2 + x3 ≤ 200;
0 ≤ x1 ≤ 100; /I suppose You have a misprint here, You’ve meant chickens instead of turkeys/
0 ≤ x2 ≤ 100;
0 ≤ x3 ≤ 25;
I solved it with a simplex-method on my computer and obtained the optimal solution:
x1 = 100 (chicks); x2 = 75 (ducks); x3 = 25 (turkeys);
maximum profit = 7875.
