Question

A store owner who bought comforters for x dollars is marking them up 60%. Write two expressions that represent the selling price and show that they are equivalent.

Answer 1

`(1+(60)/(100))x`

and

`(1+0.6)x`

Explanation:

The cost price is
`x` dollars.

The marked up price
`(60)/(100) x`

The selling price is
`x+(60x)/(100)`

This is the same as
`(1+(60)/(100))x`

This can again be written as
`(1+0.6)x`

All this are equivalent because
`1.6x`
