CONTENT OF THE LESSON  

LESSON ONE – INTRODUCTION 

Teacher’s/Pupil’s Activities 1 – Simply Interest

Teacher’s comments – To start a business, someone needs money. Mention places where ones can get money to start a business.

 

Expected Response

We can get money from savings, family and friends, donations, gifts, bank, etc.

 

Teacher’s remark – We can borrow money from family and friends with or without interest. We can also borrow from the banks with interest. This interest is called simple interest. Simple interest is a quick and easy method of calculating the interest charge on a loan or investment. 

 

 

Teacher’s/Pupil’s Activities 2 – Simple Interest 

Find the The trader Invests ₦2000 in a company that produces and sells cap. How much Interest will he get after 2 years at 10% per annum?

First, find the 10% of ₦2000

= ₦2000 x 10/100

= ₦200

Secondly,

Multiply your result by 2

= ₦200 x 2

= ₦400

 

Or

 

Interest

= (₦2000 x 2 x 10)/100

= ₦20 x 2 10

= ₦400

 

Teacher’s remark – The ₦2000 is known as the principal, (P). 10% is known as the rate (R) while 2 years is known as time (T).

Therefore, Simple Interest (I) = (P x R x T)/100

 

Pupil’s Activities 2 – Simple Interest 

A trader borrowed ₦3000 for 2 years at 9% per annum is found. Find the simple interest.

I = (P x R x T)/100

Where P = ₦30 000, Rate = 9% and Time = 2 years 

I = (₦3000 x 9 x 2)/100

= ₦30 x 9 x 2

= ₦540

1. An investor invested ₦250 for 5 years at 5%, Find the total amount received at the end of 5 years.
