The Correct Answer and Explanation is:
The correct sale price of the can of soup is $0.12.
To determine the final sale price, you must first calculate the value of the 80% discount and then subtract it from the original price. The original price of the can of soup is $0.60.
First, we find the discount amount. The discount is 80% of $0.60. To calculate this, you can convert the percentage to a decimal by dividing it by 100. So, 80% becomes 0.80. Now, multiply this decimal by the original price:
0.80 × $0.60 = $0.48
This means the discount is $0.48, or forty-eight cents. This is the amount of money being taken off the original price. It is not the final price.
To find the final sale price, you subtract the discount amount from the original price:
$0.60 (original price) – $0.48 (discount) = $0.12 (sale price)
Therefore, the final cost of the can of soup after the 80% discount is $0.12.
An alternative method is to determine the percentage of the price you will actually pay. If the item is 80% off, you are responsible for paying the remaining 20% of the price (100% – 80% = 20%). You can then calculate 20% of the original price. Convert 20% to its decimal form, 0.20, and multiply it by the original price:
0.20 × $0.60 = $0.12
Both methods confirm that the sale price is twelve cents. The key is to remember that a discount reduces the price, so the final answer must be smaller than the starting price of $0.60.
