Answer:
the approximate APY of the account is 2.73%
Explanation:
We know the formula for APY which is given by
![APY=(1+(r)/(n) )^n-1](https://img.qammunity.org/2021/formulas/mathematics/middle-school/2g47k7cwq40zx0dac9fqjz4zu90py0wmg3.png)
here, r= interset rate = 2.7% = 0.027
n = compounding cycles = 4
On plugging these values in the above formula, we get
![APY=(1+( 0.027)/(4) )^4-1](https://img.qammunity.org/2021/formulas/mathematics/middle-school/yn3cn4xo4lalaj82qter696l0wnufs2kzs.png)
![=(1+0.00675)^4-1\\\\=(1.00675)^4-1\\\\1.027274607-1\\\\=0.02727](https://img.qammunity.org/2021/formulas/mathematics/middle-school/4du3ufgtaotjaaz70ysbto0uxu2p0yq8oo.png)
On simplifying this we get
0.02727 = 0.02727*100
= 2.73%
Therefore, the approximate APY of the account is 2.73%
