Compound interest is the interest on a loan or deposit calculated based on the initial principal and the accumulated interest from the previous period.

Given

Rate (r) = 2.7%

Principal (P) = $3,500

Time (t) = 3 years

To find

The compound interest.

How do find the compound interest?

We know the formula of compound interest,

[tex]\rm Amount = Principal (1 + \dfrac{Rate}{100})^{time}[/tex]

Then put the values,

[tex]\rm Amount = 3500(1 + \dfrac{2.7}{100})^{3}\\\\\rm Amount = 3500(1.027)^{3}\\\\Amount = 3791.22[/tex]

Then the amount and APY are $3791.22 and 12.68%.
