Part A Choose an expression that can represent the sale price of the boots where x is the original price of the boots (0.2x, 0.8x, 1.2x) Part B Thus means that the sale price of the boots is (20%, 80%, 120%) of the original. cost

Answer 1

Part A: 0.8x

Part B: 80% of the original price.

Explanation:

Part A:

The store sells the boots at a sale price of 20% off, meaning the price of the shoes is 100% - 20 % = 80% of the original price. If we call x the original price, then the sale price would be

`(80)/(100)* x`
`=0.8x`

Part B:

The sale price of the boots is 100% - 20% = 80% of the original price.
