Best ResponseYou've already chosen the best response.1If you have a calculator, you can try entering '1' then hitting x2 a bunch of times (counting how many times you do so.)

Best ResponseYou've already chosen the best response.1Of course, that will only get you the per day earnings. You'll have to add up all the previous days' to get the total.

Best ResponseYou've already chosen the best response.0Let x be the amt u earn per day... Then, in 1 day: 1cent = 2^0 cents 2 days: 2 cents = 2^1 cents 3 days: 4 cents = 2^2 cents 4 days: 8 cents = 2^3 cents... So, in n days, you get 2^(n1) cents
