a toy store's gross profit on a computer game was 10 percent of the cost of the game . if the stor increase the selling price of the game from 44 to 46 and the cost of the game remained the same, then the store's gross profit on the gamer after the price increase was what percent of the cost of the game?

10.5%

11%

12.5%

13%

15%

sweetcorns

the cost of the game: x
x(1+10%)=44 --> x=40

when the selling price of the game is 46, the profit should be:

46-40=6

so: 6/40=15%
