The annual effective rate is 13.610631%. Convert its accumulation factor to four equal quarters and multiply the quarterly rate by four.

i(4)=4[(1+i)1/41]i^{(4)}=4\left[(1+i)^{1/4}-1\right]
i(4)=0.1296641528i^{(4)}=0.1296641528

Answer

Answer

The nominal annual rate convertible quarterly is approximately 13.0%, selecting choice B.

i(4)13.0%(B)\boxed{i^{(4)}\approx13.0\%\quad\text{(B)}}
