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.

The 10% reduction in price is calculated as a percent of the original price. Think of the original price as 100%. Subtracting 10% from it makes 90%. So, 90% of the original price must equal $14.40.

(original price) - (reduction in price) = sale price

(original price) - (% discount)(original price) = $14.40

100%(original price) - 10%(original price) = $14.40

90% · (original price) = $14.40

0.9 · (original price) = 14.40

original price = 14.40 ÷ 0.9

original price = 16

(you can put 16 or $16.00)
