Final answer:
To find the percent of increase in the price of the shirt, subtract the original price from the increased price, divide the difference by the original price, and multiply the result by 100 to get the percentage. The percent of increase in the price of the shirt is 22.95%.
Step-by-step explanation:
To find the percent of increase in the price of the shirt, we need to calculate the difference between the original price and the increased price, and then divide that by the original price. Finally, we multiply the result by 100 to get the percentage.
Step 1: Subtract the original price from the increased price: $18.75 - $15.25 = $3.50
Step 2: Divide the difference by the original price: $3.50 / $15.25 = 0.2295
Step 3: Multiply the result by 100 to get the percentage: 0.2295 x 100 = 22.95%
Therefore, the percent of increase in the price of the shirt is 22.95%.
