LynBrook West is an apartment complex that has 100 apartments available for rent. The monthly profit (in dollars) acquired from renting X apartments is given by P(x) = -10x^2 + 1760x - 50000. Assuming that 50 apartments have already been rented, what is the actual profit realized from renting the 51st apartment? OP(51)- P(50) = $13750 - $13000 = $750 (gain of $750) OP (51) P' (50) = $740 $760 = $20 (loss of $20/apartment) OP (51) $740 OP(51)= $13750
