Final answer:
Using the formula for future value with compound interest, the $30,000 bond at a 6% interest rate compounded semiannually will be worth approximately $86,948.92 in 18 years, when rounded to the nearest cent.
Step-by-step explanation:
To calculate the future value of a bond that pays 6% interest compounded semiannually, we use the future value formula for compound interest:
FV = P (1 + r/n)^(nt)
Where:
- P = initial principal balance ($30,000)
- r = annual interest rate (0.06)
- n = number of times the interest is compounded per year (2)
- t = time in years (18)
Plugging the numbers into the formula:
FV = $30,000 * (1 + 0.06/2)^(2*18)
FV = $30,000 * (1 + 0.03)^(36)
FV = $30,000 * (1.03)^36
FV = $30,000 * 2.8982972498
FV = $86,948.91749
Thus, in 18 years the bond will be worth approximately $86,948.92 when rounded to the nearest cent.
