Answer:
To find the percent increase in price, we need to calculate the difference between the original price and the new price, and then express that difference as a percentage of the original price.
The original price of the sweatshirt was $40, and the new price is $65, so the difference is:
$65 - $40 = $25
To express this as a percentage of the original price, we divide the difference by the original price and multiply by 100:
($25 / $40) x 100% = 62.5%
Therefore, the percent increase in the price of the sweatshirt is 62.5%.
