Question

An item costs `n` dollars. If the price of the item increases by 25%, the new price can be represented by the expression `n+0.25n`. What expression can also represent the new price?

Answer 1

See a solution process below:

Explanation:

There are a couple of other expression I can think of.

First, `0.25 = 25/100` so we could write:

`n + 25/100n`

We can also factor out `n` from each of the terms in the original expression giving:

`1n + 0.25n => (1 + 0.25)n =>`

`1.25n`
