Answer
Step-by-step explanation:
This is exponential growth, so we would use the following equation
y=a(b)^x
500(1.005)^15
1. Initial amount is $500, since that's what we started with.
2. Add the following percentage by 100%
100%+0.5%= 1.005
3. We need to find the account balance after 15 months so raise it to the 15th power.
y= 500(1.005)^15
The balance after 15 months will be $538.84.
