Answer: The percentage decrease is 55%.
Explanation: To find the percentage decrease in price, we can use the formula:
Percentage decrease = (original price - new price) / original price * 100
In this case:
Original price = $80
New price = $36
Using the formula:
Percentage decrease = (80 - 36) / 80 * 100
Simplifying the calculation:
Percentage decrease = 44 / 80 * 100
Calculating the percentage:
Percentage decrease = 0.55 * 100
The percentage decrease is 55%.
