^ if teh above is correct:

A manufacturing company operates its two available machines to polish its metal products. The two machines are equally efficient, although their maintenance costs are different. The company's daily maintenance and operating costs are given in dollars as:

f(x1, y) = 60 - x - 1.2y + 0.05(x^2) + 0.1xy + 0.07(y^2)

where x and y are the hours of operation of the two machines. Find the number of hours to operate each machine in order to minimize daily cost.

(Also requires differentiation, of a different sort

)
