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.
