If a product's price decreases from $80 to $64, what is the percentage decrease?

Step 1: Identify the original price of the product, which is $80.
Step 2: Identify the new price of the product after the decrease, which is $64.
Step 3: Calculate the amount of decrease by subtracting the new price from the original price: 80 - 64 = 16.
Step 4: Divide the amount of decrease (16) by the original price (80): 16 / 80.
Step 5: Calculate the result of the division: 16 / 80 = 0.2.
Step 6: Convert the decimal result (0.2) to a percentage by multiplying by 100: 0.2 * 100 = 20.
Step 7: The percentage decrease is 20%.
