Answer:
12.55%
Explanation:
APY = [tex](1 + \frac{r}{n} )^{n}[/tex] - 1
Where;
r = 12% = 0.12
n = 4, As the rate is compounded quarterly so n will be 4 per year.
APY = [tex](1 + \frac{0.12}{4} )^{4} -1[/tex]
APY = [tex](1 + 0.03)^{4} -1[/tex]
APY = [tex](1.03)^{4} -1[/tex]
APY = 1.12550881 - 1
APY = 0.12550881
or
APY = 12.55%
