Question

Amanda borrows £1200. She has to pay 21% per year simple interest. How much interest will Amanda have to pay in 3 years?

Answer 1

Answer:

756

Step-by-step explanation:

21% of 1200 is 252

252 x 3 = 756

Answer 2

Using the equation of compound interest, i.e.;
A=P(100+%/100)
We simplify and substitute, and get:
A= 2125.8732
So, you answer is £2125.8
