Triss [41]

Answer:

After 2 years Miguel will have in his account $541.64

Step-by-step explanation:

The formula for calculating compound interest continuously is:

A=pe^{rt}

Where A is the amount of money obtained after t years.

r is the compound interest rate and p is the initial amount

In this case we have that:

p=\$500\\\\t=2\ years\\\\r=0.04

Then we must find the final amount A

A=500e^{0.04(2)}

A=\$541.64
