As per the problem,
Rhonda 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.....(1)](https://tex.z-dn.net/?f=%20A%3DP%281-r%29%5Et.....%281%29%20)
Here we have
P=$800
r=20%=0.20
t=2 years
Substitute the values in equation (1) we get
![A=800(1-0.2)^2\\ \\ \Rightarrow A=800(0.8)^2\\ \\ \Rightarrow A=800*0.64\\ \\ \Rightarrow A=512\\](https://tex.z-dn.net/?f=%20A%3D800%281-0.2%29%5E2%5C%5C%20%5C%5C%20%5CRightarrow%20A%3D800%280.8%29%5E2%5C%5C%20%5C%5C%20%5CRightarrow%20A%3D800%2A0.64%5C%5C%20%5C%5C%20%5CRightarrow%20A%3D512%5C%5C%20)
The laptop be worth in two years will be $512.
300,000 because you have to just multiply 150 by 200
