SAC = STC/y = (w1(y/240)^2 + 48w2) / y
= (w1)(y/240)^2(y) + ((48)(w2))/y
= (w1)(y/240)^2 + ((48)(w2))/y <-- this is the final answer, but I don't understand it because of this part:
(w1)(y/240)^2(y) -> (w1)(y/240)^2
Don't you add exponents when you multiply variables? So wouldn't it become...
Note: w1, y, w2 are variables
