on day one you have one double it so on so on. after 30 days add them all up and i think the answer is 1073741823
This would be doubling the the previous days amount for 30 days: (1)1 - (2)2 - (3)4 - (4)8 - (5)16 - (6)32 - (7)64 - (8)128 - (9)256 - (10)512 - (11)1024 - (12)2048 - (13)4096 - (14)8192 - (15)16384 - (16)32768 - (17)65536 - (18)131072 - (19)262144 - (20)524288 - (21)1048576 - (22)2097152 - (23)4194304 - (24)8388608 - (25)16777216 - (26)33554432 - (27)67108864 - (28)134217728 - (29)268435456 - (30)536870912 Then I re-read the question (and quoted the main piece): If you double "a penny" everyday and add it to the previous days total for 30 days Which means the 1st day you would have doubled your penny. Then the next day you double 1 of the 2 pennies which give you 3 pennies and add it to the previous days total which gives you 5 and so forth and so on....: (If you want to get technical on how the question was written!) (1)2 - (2)5 - (3)11 - (4)23 - (5)48 - (6)97 - (7)195 - (8)391 - (9)783 - (10)1567 - (11)3135 - (12)6271 - (13)12543 - (14)25087 - (15)50175 - (16)100351 - (17)200703 - (18)401407 - (19)802815 - (20)1605631 - (21)3211263 - (22)6422537 - (23)12845065 - (24)25690131 - (25)51380263 - (26)102760527 - (27)205521055 - (28)411042111 - (29)822084223 - (30)1644168447 Can I have a round of applaud please...(clapping)...! Thank You and Good Night! I think the question states that if you double a penny every day not doubling the total of penny's there! There for you have a common denominator of 2 every day! then you add previous days amount! day 1(2) day 2(4) so forth and so on! with a total of 60 penny's So there for double a penny meaning double 1 penny every day for 30 days witch is 2 pennys every day plus the total from the day before!
The value in dollars will be $0.01 x 229 The number of pennies you will have is 229
In a few weeks I would be very rich. Each day I would have twice as much as the day before. By day 10 I' d have but five dollars ($5.16) but by day 20 over 5 thousand dollars ($5 242.88) and after a month, 30 days, five million dollars! ($5 368 709.12) (229)
30:00!!!!!

The math equation to calculate the amount of money after 30 days with a penny doubling daily can be expressed as: Amount = 0.01 * (2^30) In this equation, "2^30" represents 2 raised to the power of 30 (i.e., doubling daily for 30 days). The result will give you the amount of money accumulated after 30 days.
on day one you have one double it so on so on. after 30 days add them all up and i think the answer is 1073741823
If the first dollar was yours, then you would have $1,073,741,824 after 30 days.(When you take this number into class, don't forget to also prepare an answerfor the question "How did you figure that out ?")
