Simple Interest = Principal x Rate x Time Where: Principal = N25,000, Rate = 2% or 0.02 and Time = 5 years Plugging in the values: Simple Interest = N25,000 x 0.02 x 5 Simple Interest = N25,000 x 0.1 Simple Interest = N2,500 To find the total amount at the end of 5 years, we add the simple interest to the principal: Total Amount = Principal + Simple Interest Total Amount = N25,000 + N2,500 Total Amount = N27,500 Therefore, at the end of 5 years, the total amount would be N27,500.
