2) In what time will the sum of money be two times itself at 12% per year at simple interest rate?
a) 50 months
b) 25 months
c) 100 months
d) 75 months
e) 200 months
I did this problem and got C. I used the formula 100= 100(.12)(t)<<<silly mistake. Its double. so its 200=100(.12)(t) and that gives u 16.6667. and that is 200 months. at least ur on the right track
