anonymous · Answer

that doesn't work either.  I am sorry.

anonymous · Answer

you can do it manually by taking 1.51% of 117,000,000 and then adding it up each time.

anonymous · Answer

for instance 117,000,000*0.0151 = 1,766,700, which the total is 118,766,700.  this would be the populatoin after 1 year
