Suppose a firm earns $$10$ for every employee they hire at $$\frac{8}{h}r.$

They earn $$25$ for every $$20$ they spend on capital.

From this we know that the firm is producing at:

Profit$-$maximizing point and a least$-$cost point

Profit$-$maximizing point but not a least$-$cost point

Least$-$cost point but not a profit$-$maximizing point

Neither profit$-$maximizing nor least$-$cost point
