Term 3 Week 5 (Monday)

Assignment
1) Math AB 3.7
2) Parachute Essay (4 more groups)
Please type in your title, group members' name and BC.

Reminder:
I need two more Sudoku experts to take part in a competition. Please let me know if you are interested.

Questions Of the Day:

Today, when we were discussing about percentage and interest rate, Kaelan mentioned about "simple interest" and "compound interest". Unfortunately, I did not have the time and opportunity to discuss more about them.

Question 1:
Who can tell me what does compound interest mean?

Question 2:
I put $1000 in the bank and the bank pays 4% interest annually. How much money do I have in the bank account after 3 years if the money is compounded annually?
Round off answer to the nearest dollar.
(what if the interest is compounded semi-annually?)
(Maybe i will give a small reward if someone can answer the above questions correctly)
