1. Wait patiently for a helper to come along.
2. Once someone helps you, say thank you and close the thread with:

+close

3. Feel free to nominate the person for helper of the week in #helper-nominations
4. Do not ping the mods, unless someone is breaking the rules.
5. If you're happy with the help you got here, and the server overall, you can contribute financially as well:

Hi! You would have to use the annual interest rate formula. Since the interest rate is 12%, r would be 0.12 or 12/100
I think the original amount is mentionned in part 3A, so the formula would be P(1+0.12)^3
P being the starting amount the client invests. Ping me and let me know if anything is unclear!
