Final answer:
The spa decreased the price of its pedicure by 25%. The price drop was calculated by subtracting the new price from the original price and then expressing this difference as a percentage of the original price.
Step-by-step explanation:
The question is asking for the percent decrease in the price of a pedicure at a spa. To calculate the percent decrease, we first need to find the amount of the decrease. The original price was $64, and the new price is $48. So, the decrease in price was $64 - $48 = $16.
Next, we want to express this $16 as a percentage of the original price. The formula for percent decrease is (decrease/original price) * 100. Plugging in our numbers: (16/64) * 100 = 25%.
So, the percent decrease in the price of the pedicure was 25%.
