GCSE Maths - How to Calculate Simple Interest #95

The video tutorial explains how to calculate simple interest using examples. It starts with a basic example of lending 200 lbs at a 3% interest rate and calculates the total amount owed after one and two years. The tutorial then extends the example to a 10-year period, showing how to multiply the annual interest by the number of years. Finally, it presents a different scenario where Dora invests 600 lbs at a 2.1% interest rate for six years, demonstrating the calculation of total interest and final amount.
