Question

For sale, a store decreases its price on all items by 25%. An item that cost $120 before sale now costs $120 - 0.25($120). Use the distributive property to write an equivalent expression for the items cost now.

Answer 1

see the explanation

Explanation:

we have

`120-0.25(120)`

Applying the distributive property

`120-0.25(120)=120[1-0.25]`

`=120[0.75]` ----> equivalent expression

Let

x ----> the cost before sale for the items

A general expression for the items cost now is

`x[0.75]`
