thankyou your. the best. i actually calculated the answer on some random website and it took me a while but i got 7.69% as an interest rate but the thing is on the website it didn't have any working out or formula's it just gave me the answer. i klnew it was right. and i think all you needed to do was multiply your final answer by 2 and i got the answer. so i'm very much appreciative of your work. you've helped me so much. i hope good things come to you... again thankyou. your a legend
