Answer:
2.18%
Explanation:
Effective interest rate = (1+i/m)^n - 1
i is stated as interest rate
m is the compounding frequency
Here, the compounding is quarterly and the effective interest rate is 8%
Since one year is equal to 4 quarter, the value of m is equals to 4
Effective interest rate = (1 + i/4)^4 - 1
9% = (1 + i/4)^4 - 1
0.09 + 1 = (1 + i/4)^4
(1.09)^1/4 = 1 + i/4
1 + i/4 = 1.02178
i/4 = 1.02178 - 1
i/4 = 0.2178
i/4 = 2.18%
