Question

1CollegeMathematics 5 pointsRhonda bought a new laptop for $800. The laptop depreciates, or loses, 20% of its value each year. The value of the laptop at a later time can be found using the formula A=P(1−r)t AP 1 r t , where P is the original value, r is the rate of depreciation written as a decimal, and t is the number of years since it was purchased. What will the laptop be worth in two years?

Answer 1

Given that Value of laptop P= $800

Rate of depreciation r=20%= 0.20

We have to find value of laptop after two years so time t=2

Now plug those values into formula:

`A=P(1-r)^t`

`A=800(1-0.20)^2`

`A=800(0.80)^2`

`A=800(0.64)`

`A=512`

Hence the final answer is $512.
