Suppose that 2000 is invested at a rate of 2.4% , compounded semiannually. Assuming that no withdrawals are made, find the total

gtnhenbr [62]

Answer:

$2479.02

Step-by-step explanation:

The invested amount is $2000 at a rate of 2.4% which compounds semiannually.

Therefore, the semiannual interest rate is $\frac{2.4}{2} = 1.2$ %.

Then the principal is compounded (9 × 2) = 18 times within a period of 9 years.

If there is no withdrawal from the account, then after 9 years the sum will become

$2000(1 + \frac{1.2}{100} )^{18} = 2479.02$ dollars {Rounded to the nearest cent} (Answer)
