To find the principal for each year, we can calculate the principal by decreasing the previous year's principal by 4.5%.
Starting with the initial principal in year 0:
- Year 0: $320,000.00
Calculations:
-
Year 1: \[ \text{Year 1 Principal} = \text{Year 0 Principal} \times (1 - 0.045) \] \[ \text{Year 1 Principal} = 320,000 \times (1 - 0.045) = 320,000 \times 0.955 = 305,600.00 \]
-
Year 2: \[ \text{Year 2 Principal} = \text{Year 1 Principal} \times (1 - 0.045) \] \[ \text{Year 2 Principal} = 305,600 \times 0.955 = 291,616.00 \]
-
Year 3: \[ \text{Year 3 Principal} = \text{Year 2 Principal} \times (1 - 0.045) \] \[ \text{Year 3 Principal} = 291,616 \times 0.955 = 278,085.28 \]
Completed Table:
| Year | Principal | |------|------------------| | 0 | $320,000.00 | | 1 | $305,600.00 | | 2 | $291,616.00 | | 3 | $278,085.28 |
So the principal amounts for years 1, 2, and 3 are:
- Year 1: $305,600.00
- Year 2: $291,616.00
- Year 3: $278,085.28
