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

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
00 x 10/1 00
Multiply your result by 2
= ₦200 x 2
00 x 2 x 10)/1 00
= ₦20 x 2 10
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 = (₦30
00 x 9 x 2)/1 00
= ₦30 x 9 x 2
