Simple Interest

I have 400 in the Bank. At the end of each year

I receive 7 of 400 in interest. How much

interest do I receive after 3 years. How much do

I now have?

Calculating Percentages

Interest calculated on new value every year

Int 2

Compound Interest

Real life Interest is not a fixed quantity year

after year. One years interest becomes part of

the next years amount. Each years interest is

calculated on the amount at the start of the year.

Daniel has 400 in the bank. He leaves it in the

bank for 3 years. The interest is 7 each year.

Calculate the compound interest and the amount he

has in the bank after 3 years.
