Answer:
$45,000
Explanation:
Cully's storage constraint is: 100B + 90M ≤ 18000
If Cully were to buy only big shelves, it could buy 180 of them (= 18,000 / 100)
If they were to buy only medium shelves, it could buy 200 (= 18,000 / 90)
Cully's money restraint is: 500B + 300M ≤ 75,000
If Cully were to buy only big shelves, it could buy 150 of them (= 75,000 / 500)
If they were to buy only medium shelves, it could buy 250 (= 75,000 / 300)
So Cully's order must be within 150 big shelves and 200 medium shelves.
If Cully purchases and sells 150 big shelves, it will earn $45,000 in profit.
If Cully purchases and sells 200 medium shelves, it will earn $30,000 in profit.
Since the profit for big shelves is $500, Cully should try to sell as many of them as possible. The maximum amount that they can buy is 150, which will result in a $45,000 profit.
