profit=52.50*987 -(11450+19.75*987)

only challenge is calculation..lets simplified

profit= (52.5-19.75)*987 -11450
=32.75*987 -11450
=32.75 *(1000-13) -11450
= 32750 -11450 -32.75*13
=21300 - 32.75*13 (no need to calculate here..answer option are far apart)
looking at the answer it should be A

If you solve this problem with full multiplication then you wont be able to solve it in 2 minutes. I used approximation and answer should be A.
Make $20 per unit for production. And $50 per unit for sale. Then the profit is coming out to be 18000. But because we reduced the selling cost by $2 per unit and there are 987 so the only answer close to it is A.
