To determine the worth of the copy machine in 10 years, we can assume a straight-line depreciation based on the given values.
- At year 0, the value of the machine is $10,500.
- At year 5, the value of the machine is $5,500.
We can calculate the annual depreciation first:
\[ \text{Depreciation over 5 years} = 10,500 - 5,500 = 5,000 \]
\[ \text{Annual depreciation} = \frac{5,000}{5} = 1,000 \]
Now, we can find out the value of the machine at 10 years:
\[ \text{Depreciation from year 5 to year 10} = 1,000 \times 5 = 5,000 \]
\[ \text{Value at year 10} = 5,500 - 5,000 = 500 \]
Thus, after 10 years, the copy machine will be worth $500.
The correct response is: After 10 years, the copy machine is worth $500.
