The stores ranked from the cheapest to most expensive sale price for the watch is :  A, D, B, C.

A discount reduces the price of an item. The formula that can be used to determine the price after a discount is: initial price x (1 - discount rate)

Price after discount

Store A: $129.99 x (100 - 25%)

$129.99 x 0.75 = $97.49

Store B: $119.99 x (100 - 15%)

$119.99 x 0.85 = $101.99

Store C:

Price after the first discount = $115 x (100 - 5%)

115 x 0.95 = $109.25

Price after the second discount = $109.25 x (100 - 5%)

$109.25 x 0.95 = 103.79

Store D:

$109.99 x (100 - 10%)

$109.99 x 0.90 = $98.99
