Question

A laptop computer is purchased for $1500 after each year the resale value decreases by 25% what will the resale value be after three years

Answer 1

The resale value after three years = $ 632.8125‬

Step-by-step explanation:

Given the laptop purchase for $1500

Therefore, the cost price = $1500

According to the question, the resale value decreases by 25%,

Then after three years, the resale value is

Resale Value =
`\text { cost Price }\left(1-(r)/(100)\right)^{\text {time }}`

Substituting the values,

Resale Value =
`1500\left(1-(25)/(100)\right)^(3)`

Resale Value =
`1500* ((3)/(4))^3`

Resale Value =
`1500* (3)/(4)* (3)/(4)* (3)/(4)`

Resale Value = $632.8125‬

Therefore, the resale value after three years = $ 632.8125‬
