Answer:
$31.37 is the sale price
Step-by-step explanation:
All you need to do to find the discount price (sale price) is multiply the price of the item by the decimal form of the percentage.
1. Store A. 40% off the original price of $159.99

63.996 is the discount price we are looking for
2. Store B. 25% off the original price of $130.50

32.625 is the discount price we are looking for
3. Now to find their difference you just subtract the two values.

The discount price (sale price) is $31.371
It’s 28 divided by 7 x 15 -13
