Hi All,
We're told that a toy store's gross profit on a computer game was 10 percent of the cost of the game and the store increased the selling price of the game from $44 to $46 and the cost of the game remained the same. We're asked to find the store's gross profit on the game after the price increase as a percent of the cost of the game. The answer choices to this question are 'spread out' enough that we can use a bit of logic (and a little math) to get to the correct answer.
Since the initial selling price of the game is $44 - and that represents a 10% PROFIT - we know that the COST of the game is LESS than $44. Thus, raising the sell price by $2 will increase the profit by $2.
$2/$44 = 1/22 = about 5% - and since we know that the COST was less than $44, 1/22 would be 'rounding down' (the actual fraction is likely closer to 1/20). Thus, the INCREASE in profit (as a percent of cost) is almost certainly around 5%. There's only one answer that's that much greater than the initial 10% profit we started with...
Final Answer: E
