A shirt originally cost $47.26, but it is on sale for $44.90. What is the percentage decrease of the price of the shirt?

Answer: 5%

Step-by-step explanation: In order to calculate the percentage of the discount we need to first calculate the amount of the discount.

$47.26 - $44.90 = $2.36 discount amount

In order to calculate the percentage of the discount you must divide the discount amount by the original cost.

$2.36 / $47.26 =.0499 = rounded off to a 5% discount

The decrease is by 5%.
