Problem:
Use the simplex method for solving nonstandard problems to solve the given linear programming problem.
Minimize C = x + 2y
Subject to 4x + 5y ≤ 70
2x + y ≥ 20
x ≥ 0, y ≥ 0
a. x = 5, y = 10, C = 25
b. x = 0, y = 5, C = 4
c. x = 0, y = 0, C = 0
d. x = 10, y = 0, C = 10
Additional Information:
This problem is basically from Mathematics as well as it is about how to solve linear programming by using simplex method.
