Answer:
The approximate value of machine after 3 years = $12283
Explanation:
Original cost of the copy machine = $20,000
Rate of depreciation each year = 15%
To, find cost of machine after 3 years.
Solution:
The depreciation equation can be given by:
![V=V_o(1-r)^t](https://img.qammunity.org/2020/formulas/mathematics/middle-school/luw6fcidkwtu1kdqfsa030s2fjtndzbh2g.png)
where:
Final value
Original value

time
Given values:
![V_o=\$20,000\\r=15\%=0.15\\t=3\ years](https://img.qammunity.org/2020/formulas/mathematics/middle-school/6otwiehyxloo6cu84bianr7coy8tovqo3j.png)
Using the values to find the value of machine after 3 years.
![V=20000(1-0.15)^3](https://img.qammunity.org/2020/formulas/mathematics/middle-school/bzdh2jaes5jgb1e00pqh732a2xf97pojfs.png)
![V=20000(0.85)^3](https://img.qammunity.org/2020/formulas/mathematics/middle-school/dkqwgvu9xhoal1e6gxfo6yxtrciivstnl3.png)
![V=20000(0.614)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/c1o0qa0s2r2w9vb2qnu67hd5g16lg9rlo4.png)
![V=12282.5\approx12283](https://img.qammunity.org/2020/formulas/mathematics/middle-school/hzfsftf9lbx26omwh29cae9bem8yyxtewe.png)
Thus, approximate value of machine after 3 years = $12283
