A. should hire more of both X and Y
B. should hire more of Y and less of X

Answer:

C. is producing with the least-costly combination of X and Y,but could increase its profits by employing more of X and less of Y

Explanation:

At equilibrium

We know that

MRPx ÷ MRPy = wx ÷ wy

So, according to the question, it is

100 ÷ 6< 50 ÷ 20

This means that MRPx ÷ wx > MRPy ÷ wy

In this way, the equilibrium x would be rise and y would be decreased

Therefore the correct option is c.

And, the rest of the options would be seems wrong
