Step-by-step explanation
The compounded interest is given by the following expression:

Where a=Principal=800, r=interest rate in decimal form=3/100=0.03 n=number of times compounded in a year = 360:
We assume 360 because the account is compounded continuously, the model would be as shown as follows:

b) We can see that the y-intercept is at (0,800) and it represents the Initial Capital.
c) The balace in 5 years will be give by the following relationship:



Multiplying numbers:

The balance in 5 years will be of $929.46
d) Comparing to another account compounded monthly, n=12:



Multiplying numbers:

In conclusion, after 5 years, the investment will be almost the same, just a bit lower than continuously compounded.
