Tina starts with $.10 and put it in her piggy bank in January then she doubles it in February to put in $.20 if she keeps doubling the amount she puts in her bank each month how much will she have in her bank by the end of December
The correct answer would be $204.80 because if she keeps doubling whats in the bank the amount after the $ .20 then it would be doubled to $ .40 and so on
