Mr. Raza, a drug store retailer, sells surgical face masks and KN95 masks. He can regularly acquire a supply of 200 to 400 surgical masks and 100 to 150 KN95 masks but not more than 500 items altogether. Mr. Raza can buy the surgical masks wholesale at Php10 each and sell them for Php18 each, whereas the KN95 masks cost Php25 each at wholesale but can be sold for Php 35 each. Mr. Raza wants to maximize his profit in the sales of the surgical face masks and KN95 masks. If you let x be the number of surgical masks and y the number of KN95 masks to be acquired by Mr. Raza, which among the following is a constraint in this problem? 200 ≤ y ≤400 100 < y < 150 200 ≤ x ≤ 400 x + y > 500
