To find: Show the ratio of depreciation amounts for consecutive years is constant then write an equation that gives
The equation becomes
Given information:
Given that
Depreciation amount for consecutive years is below:
Year (t) | 1 | 2 | 3 | 5 | 5 |
Depreciation(d) | 1906 | 1832 | 1762 | 1692 | 1627 |
Calculation:
The exponential decay model is
Now find the ratio of depreciation between consecutive years:
Therefore the decay factor
Now the initial amount when
In the decay model
This is the required equation.
