How much money would you have in an account after 15 years if you earned 9,3% annually and you started with R573,00?​

Given:

Principal = R573.00

Rate of interest = 9.3% annually

Time = 15 years.

To find:

The amount after 15 years.

Solution:

Where, P is principal, r is the rate of interest in decimal, n is the number of time interest compounded in an year and t be the number of years.

The interest is compounded annually, so n=1.

Putting in the above formula, we get

Therefore, the amount in the account after 15 years is about  R2174.99.
