Potato....how would you find the %?

To find the percent of decrease, you need to compare the difference between the original cost and the new cost to the original cost and convert it to a percentage.

Step 1: Find the difference between the original cost and the new cost.
$65 - $57.20 = $7.80

Step 2: Divide the difference by the original cost.
$7.80 / $65 = 0.12

Step 3: Convert the decimal to a percentage by multiplying it by 100.
0.12 x 100 = 12%

Therefore, the percent of decrease is 12%.
