The price of a shirt is marked down from $12.50 to $10,00. What is the percent decrease of the shirt?
choli [55]

Answer: 20%.

Step-by-step explanation:

Given, The price of a shirt is marked down from $12.50 to $10.00.

Previous price = $12.50

New price = $10.00

Change in price = Previous price - New price

= $12.50 - $10.00

= $2.50

Now, the percent decrease of the shirt = \dfrac{\text{Change in price}}{\text{Prevoius price}}\times100

=\dfrac{2.50}{12.50}\times100\\\\=20\%

Hence, the percent decrease of the shirt = 20%.
