Question

1. Given the objective function and constraint equation, use the Method of Lagrange Multipliers to obtain an optimal solution of the following:

y= 20A + 101.5V

phi= A(230-47.7/V)-5556 = 0

2. If energy requirement increases by 1 % to 2.02 x 108 J use the Lagrange multiplier to estimate the change in the first cost.
