I want to ask another question related to this one. If the interest is not the simple interest, but the compound interest, how to get the answer in this question? ( n is equal to 12 or less than 12; n is more than 12)
Thank you!
revenue for compound interest(principal not included), d[(1+k/12)n-1].
k represents "persent" , I think that the answer should be d[(1+k/1200)n-1].
