If i give you one penny one day two the next day and keep doubling it for one year how much money would it equal?
If you keep doubling it for one month, you will already have 10737413,11 dollars.
What is better getting 100000 at once or getting a penny whose sum is doubled everyday for 31 days?
Take the penny a day doubled every day. The sum would be almost 43,000,000.
What is the equation for a penny doubling every day for a year?
The equation for the amount you have reached on a given day is 2n-1, where n is the days since starting. For example, on the first day 21-1 = 1 penny, while 2200-1 = 8.035 x 1059 pennies on the two-hundredth day, and 2365-1 = 3.758 x 10109 pennies on the last day. The equation for the whole amount is Σ1365 (2n-1), where the sigma represents the sum of a series and the range is from day 1 to day 365. : Another way of looking at it, which doesn't involve scary "sigma" signs, is this: Whereas X is set equal to "the number of pennies one would receive on the last day of the year after starting with one penny and doubling it every day", then X would equal 2 to the 364th power. 2 to the zeroth power is one. First day. 2 to the first power is two. Second day. 2 to the second power is four. Third day. 2 to the third power is eight. Fourth day. Etc. Note that each power is one less than the day in question. Therefore, 2 to the 364th power would show you how many pennies you would receive on the 365th day. However, one must then perform this equation, for the total number of pennies one would have at the end of the year: 2 to the zeroth plus 2 to the first plus 2 to the second...plus 2 to the 362nd plus 2 to the 363rd plus 2 to the 364th = Y, whereas Y is equal to "the total number of pennies one would have at the end of the year". Yet, an easy short cut is to realize that one need only take the value of X (which is equal to how many pennies you receive on the last day of the year) and subtract one, in order to see how many pennies you had received on the first 364 days of the year total! Then add that amount to X, and you will have Y (which is equal to the total amount of pennies you have for the whole year). Or, X plus (X-1) = Y.
How much will you have if you saved a penny every day for a year?
365 pennies = $3.65
What does 70800 a year equal to in hours for an 8 hour day?
Depends on how many working days in a year.
