Million Dollar Riddle

[We're Back]

44inarow you cant answer this

for everyone else,

If you start off with one penny, and double your amount every day, how many days will it take for you to have a million dollars?

[We're Back]

Hint: its under 50 days

[Old Tiger]

49

[We're Back]

lol no, not 49

just do the math, its not that hard

[TAMUGRAD]

28 days:thinking:

[We're Back]

very close TAMUGRAD

[TAMUGRAD]

what am i missing? do you count day one at .01 cents or is day one .02 cents? i'll try again

[We're Back]

on day 1 you have one penny

[SwtwtrMstngs04]

30?

[TAMUGRAD]

is it something wierd like 27.5 days?

don't think it is the math, think it is something obvious that i'm missing in the wording of the question

help!!!! 44inarow

[We're Back]

its not 30, and its not a decimal answer, its a whole number of days

If it is a whole number that you want then I will go with 27, because at some point in the 27th day you will hit $ 1 million, and by the 28th day you are well over that amount so 27days is my final answer.:D

[We're Back]

and 27 days is the correct answer:D

[big daddy russ]

27 days.

TAMUGRAD, I think you're looking at when he earns $1 million in one day... if you add the combined totals up he earns it a day earlier.


Sorry, got to it a little late.

[TAMUGRAD]

Thanks Regis

[We're Back]

yeah its not a million dollars exactly, its just what day will he hit a million dollars, my bad for wording the original question wrong

[44INAROW]

We were flipping channels last night and The SuperMillionaire was on GameShow Network, and that was a $500,000 question. Talk about compounding interest quickly lol..... it just surprised us how quickly it added up..

[TAMUGRAD]

yea, when he said less than 50 days, my first thought was, no way, but do the math it works. now if we could all find something to invest in to make it work......

[We're Back]

i might just start lookin for pennies.......LOL

its 27 because you start off with one penny, but have to add two decimal places for the dollar value.
