Question

The cost of making a shirt is half of what the shirt normally sells for. today, however, the shirt is on a 15% discount from its normal price. what is the current price of the shirt?

Answer 1

Let the cost of the shirt be y and the price by the which the shirt is sold is 2y.

Now, let's calculate how much does 15% represent from the price of the shirt:
15% discount = (15/100) x 2y = 0.3y
Therefore, the shirt is sold for : 2y - 0.3y = 1.7y

This means that at 15% discount, the shirt is sold at 1.7 of its original cost.
