Answer:
.
Step-by-step explanation:
The effective rate is calculated in the following way:
![r = {(1 + \frac{i}{n} )}^{n} - 1](https://tex.z-dn.net/?f=r%20%3D%20%20%7B%281%20%2B%20%20%5Cfrac%7Bi%7D%7Bn%7D%20%29%7D%5E%7Bn%7D%20-%201)
where r is the effective annual rate, i the interest rate, and n the number of compounding periods per year (for example, 12 for monthly compounding).
our compounding period is 2 since the bank pays us semiannually(two times per year) and our interest rate is 8%
so lets plug in numbers:
3 tens is 3 * 10 = 30
9 ones is 9 * 1 = 9
30 + 9 = 39
Answer: 39
