Question

GameStop sold 120 copies of Call of Duty. This was 30% of their supply. How

many copies of Call of Duty did they have before the store opened? *

Answer 1

The store had 400 copies of the game in stock before it opened.

If 30% = 0.3, then you multiply 120 by 0.3 and you get 400.

I checked the answer by multiplying 400 by 0.3 and you’ll be back to 120.

Answer 2

415 Call of Duty

Explanation:

120*3=360 which is 90%

120/2=60

360+60=420

420=105%
