In this math lesson we will learn how to solve problems involving simple interest.

When you deposit money in a savings account, the bank pays you interest at a certain rate called interest rate. There are two types of interest: simple interest and compound interest. In this lesson we will talk about simple interest. We will use the following important formula:

I = prt

I - represents the interest (or the amount of money that the bank will pay you for allowing it to use your savings account).

p – represents the principal (the money you initially deposit)

r – represents the interest rate

t – represents the time in years.
