50%
75%

Answer 1

The percent of decrease is 33%.

Step-by-step explanation:

To calculate the percent of decrease, we need to find the difference between the original price and the new price, and then divide it by the original price. In this case, the difference is $15 - $10 = $5. Dividing $5 by the original price of $15 gives us $\frac{5}{15} = \frac{1}{3} = 0.33.

To convert this decimal into a percentage, we multiply it by 100, giving us 0.33 * 100 = 33%. Therefore, the percent of decrease is 33%.
