Question

Rayhana has a coupon for 15% off a single item at a store. If the item has a regular price of p dollars, then the sale price can be represented by p – 0.15p. Which expression is equivalent?

Answer 1

0.85pis the equivalent expression

Answer 2

`0.85p`

Explanation:

We have been given an expression
`p-0.15p`, which represents the price of an item p after a 15% off. We are asked to find equivalent expression.

We can find equivalent expression in two ways. Either by finding 85% of p (100%-15%) or factoring our p from our given expression as:

`(1-0.15)p`

`0.85p`

85% of p:
`(85)/(100)p=0.85p`

Therefore, the expression
`0.85p` is equivalent expression to our given expression.
