Answer 2

C.
`(3)/(5)`

Explanation:

Let x be the original price of laptop computer.

We have been given that Luis purchased a laptop computer that was marked down by 2/5 of the original price.

The price of laptop computer after mark-down would be x minus 2/5 of x.

`\text{The price of laptop computer after mark-down}=x-(2)/(5)x`

`\text{The price of laptop computer after mark-down}=(5)/(5)x-(2)/(5)x`

`\text{The price of laptop computer after mark-down}=(5-2)/(5)x`

`\text{The price of laptop computer after mark-down}=(3)/(5)x`

Therefore, Luis paid
`(3)/(5)` of the original price.
