Unit 4: Finance and Business math

Important Questions and Notes:

Finding Simple Interest Notes

Interest is a cost charged for the use of money borrowed or lent. If you have a savings account, you are lending your money to the bank. The money borrowed or lent is called the principal. The amount of interest earned depends on the interest rate and the length of time that the money is borrowed.

The formula for finding simple interest is Interest = Principal x Rate x Time or I=prt

Principal is the amount of money saved, lent or borrowed.

Rate is the annual percentage rate charged. (Annual = one year)

Time is the length of the loan measured and expressed in years.

Examples: 9 months = 9/12 or ¾ or .75 of a year. 18 months = 1 ½ years = 1.5 of a year.

Example: What is the interest on $200 borrowed for 3 years at 10% rate?

Interest = $200 (the principal) x .10 (the rate 10% as a decimal) x 3 (the time in years) = $60.

Note: The total amount owed back is principal + interest = $200 + $60 = $260.

1. You borrow $50 for 1 year at 5% interest rate. What is the interest owed?

The principal is ______________

The rate is __________________
