Final answer:
To find the value of Robert's investment after 4 years at a 17% annual interest rate compounded monthly, we can use the compound interest formula, which yields a value of approximately $30,082.44.
Step-by-step explanation:
To calculate the value of Robert's investment after 4 years, we can use the compound interest formula:
A = P(1 + r/n)^(nt)
Where:
- A is the future value of the investment
- P is the initial investment amount
- r is the annual interest rate (in decimal form)
- n is the number of times the interest is compounded per year
- t is the number of years
Given that Robert invested $20,600 at 17% annual interest rate compounded monthly, we can plug in the values into the formula:
A = $20,600(1 + 0.17/12)^(12*4)
Simplifying:
A = $20,600(1.01416666667)^(48)
Calculating:
A ≈ $30,082.44
Therefore, the value of Robert's investment after 4 years will be approximately $30,082.44.
