Question

Colin invests £1200 into his bank account. He

receives 3% per year compound interest. How
much will Colin have after 4 years?​

Answer 1

1,344

Step-by-step explanation: So first I multiplied 1,200 by .03 because in order to multiply by a percent you need to move it decimal back two times. After you multiply 1200 x .03 = 36. Next you would do 36 x 4 for the 4 years and it would = 144. Then you would add 144 to the original because it's interest and you would end up with Colin having 1,344.
