1. Please explain why the correct answer to this questionis calculated.
Suppose that one factory inputs its goods from two different plants, A and B, with different costs, 3 and 6 each respective. And suppose the price function in the market is decided as p(x, y) = 100 - x - y where x and y are the demand functions and 0 ≤ x, y. Then as X 48.5 x = 0 y = O 0 the factory can attain the maximum profit, X2352.25
Please show your answer to 4 decimal places. Suppose that f(x, y) = e = 3x² − 4y² + y = e then the maximum is
