Final answer:
The future value of the cash flows at the end of year 3 with a 7.25% interest rate is $10,065.49.
Step-by-step explanation:
To determine the future value of cash flows at the end of year 3 with an interest rate of 7.25%, we use the formula for compound interest:
Future Value = Principal × (1 + interest rate)time
For each cash flow:
- Year 1 cash flow future value at the end of Year 3: $6,800 × (1 + 0.0725)2
- Year 2 cash flow future value at the end of Year 3: $2,100 × (1 + 0.0725)1
- Year 3 cash flow is $0, so its future value is also $0.
Now, let's calculate these:
- Year 1 future value: $6,800 × (1 + 0.0725)2 = $6,800 × 1.14900625 = $7,813.24
- Year 2 future value: $2,100 × (1 + 0.0725) = $2,100 × 1.0725 = $2,252.25
- Year 3 future value: $0 (There are no additional calculations needed for Year 3 as the cash flow is $0.)
The combined future value at the end of Year 3 is the sum of these individual future values:
$7,813.24 (Year 1) + $2,252.25 (Year 2) = $10,065.49
This amount represents the total value of the cash flows at the end of Year 3 when they are subject to compounding at an annual interest rate of 7.25%.
