Please help I’ve been stuck on it forever. :(
slava [35]

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

(159.99 * .40) = 63.996

63.996 is the discount price we are looking for

2. Store B. 25% off the original price of $130.50

(130.50 * .25) = 32.625

32.625 is the discount price we are looking for

3. Now to find their difference you just subtract the two values.

($63.996 - $32.625) = $31.371

The discount price (sale price) is $31.371
