Final answer:
To find the sale price of an item that costs 15% of its original price, convert 15% to a decimal (0.15) and multiply it by the original price of $89. The sale price is $13.35.
Step-by-step explanation:
The student has asked about how to find the sale price of an item when it costs 15% of its original price. To calculate this, you will first need to convert the percentage to a decimal by dividing by 100, making 15% equivalent to 0.15. Then you'll multiply this decimal by the original price to find the sale price. In this case, if the original price is $89, then the sale price can be found by doing the following calculation:
Sale Price = Original Price × Sale Percentage
Sale Price = $89 × 0.15
Sale Price = $13.35
The item on sale, therefore, will cost $13.35.
