Answer:
C. 1.9090%
Step-by-step explanation:
We have been given that the APR of a savings account is 1.9% and interest is compounded semiannually. We are asked to find the APY of the account.
To solve our given problem, we will use APY formula.
[tex]APY=(1+\frac{r}{n})^n-1[/tex], where,
r = Annual interest rate in decimal form,
n = Number of times interest is compounded per year.
Let us convert our given rate in decimal form.
[tex]1.9\%=\frac{1.9}{100}=0.019[/tex]
Upon substituting [tex]r=0.019[/tex] and [tex]n=2[/tex] in APY formula we will get,
[tex]APY=(1+\frac{0.019}{2})^2-1[/tex]
[tex]APY=(1+0.0095)^2-1[/tex]
[tex]APY=(1.0095)^2-1[/tex]
[tex]APY=1.01909025-1[/tex]
[tex]APY=0.01909025[/tex]
Since APY is in decimal form, so we will multiply APY by 100 to get as percentage.
[tex]APY=0.01909025\times 100[/tex]
[tex]APY=1.909025\%\approx 1.9090\%[/tex]
Therefore, the the approximate APY of the account 1.9090% and option C is the correct choice.
