A shirt is on sale for $14.40. The sale price is 10% off the original price. What was the original price?

When a sale is 10% off, this means they subtracted 10% of the original price from the original price, and the buyers now only have to pay 90% of the price (100-10=90).

This means $14.40 is 90% of the original, so we can use ratios to figure out 100% of the price.

14.40 90%

x 100%

x = 14.40 * 100 / 90 = 16

So, 16 dollars was the original price.
