hi, i cant figure out this equation and its making me nuts, a man gets 1 cent for the first day, it doubles everyday for 34 days................................next part, when would be become a millionaire?
where M is money (in cents) and n is number of days.
So sub n = 34 and solve for M.
Sub M = (however many cents are in one million dollars) and find the first integer valuem of n such that you've got at least a million dollars. Trial and error might be the best appoach here ..... Hint: From the first part you know n < 34 ......)
