Answer:

Store Z has the best sale price of $28.

Explanation:

Original price of shoes at all stores: $35

Let's find and apply each discount and see what the discounted prices are in the 3 stores. Then we will read the choices and choose the correct one.

Store X: 15% off

Discount is 15% of $35 = 0.15 × $35 = $5.25

Discounted price is $35 - $5.25 = $29.75

Store Y: $5 off

Discount is $5

Discounted price is $35 - $5 = $30

Store Z: 1/5 of price of shoes off

Discount is 1/5 of $35 = 1/5 × $35 = $35/5 = $7

Discounted price is $35 - $5 = $28

Now we have the discount amount and the discounted price for each store. We can now read the choices.

Store X has the best sale price of $20.

False. The best sale price is not Store X. It is Store Z.

Store Z has the best sale price of $7.

False. $7 is the discount amount of Store Z, not the discounted price.

Store Z has the best sale price of $28.

True. The other discounted prices are $30 and $29.75, so Store Z has the best discounted price and it is $28.

Store Y has the best sale price of $30.

False. The best discounted price is $28, not $30.
