Which of the following represents the profit from the investment of x dollars at n percent compound annual interest for 5 years?  Choices
A) x (1+n/100)^5 - x  B) 4x (1+n/100)^4 - x  C) 6x (1+n/100)^6 - x  D) 2x (1+n/100)^2 - x  E) x (1+n/100)^7 - x
Amount after 5 years compounded yearly = x (1+n/100)^5   Thus profit = Final amount - original principle = x (1+n/100)^5 - x . x (1+n/100)^5 - xnswer : x (1+n/100)^5 - x
