Answer 1

In this case, we'll have to carry out several steps to find the solution.

Step 01:

Data

original price = $40

sale price = ?

Store X

discount rate = 20% = 0.2

Store Y

discount rate = 10% = 0.1

Store Z

discount rate = 1/8 = 0.125

Step 02:

In this case we can compare the discounts to find the solution.

Store X

Sale price = original price - original price * discount rate

= original price * (1 - discount rate)

sale price = 40 * (1 - 0.2) = $32

Store Y

sale price = 40 * (1 - 0.1) = $36

Store Z

sale price = 40 * (1 - 0.125) = $35

The answer is:

Store X has the best discount .
