Assuming that you have 1 cent before you start, and for each of the following 30 days double the number of cents, you would have 230 cents on the 30th day. In the US, this would be $10,737,418.24 USD on the final doubling.
If you keep the cents as they are doubled, then the total for all 30 days, plus your original 1 cent, will be (231 - 1) or $ 21,474,836.47 USD in all.
The prorated amount of a monthly bill of $1231.50 for 8 days of service would be $328.40. You get this by dividing the total amount by 30 days and then multiplying that amount by the eight days.
The total amount for 200.00 per day for 45 days would be 9,000.00.
If the terms are 2/10 net 30, that means you receive a 2% discount if you pay the invoice within 10 days, otherwise, the total amount is due in thirty days. So if you pay early, multiply the invoice total by 2% (.02), that is the discount amount to be subtracted from the invoice total.

Oh, dude, August has 31 days, and September has 30 days. So, like, if you add them up, that's a grand total of 61 days. Math is hard, but not as hard as trying to remember how many days are in each month!
The prorated amount of a monthly bill of $1231.50 for 8 days of service would be $328.40. You get this by dividing the total amount by 30 days and then multiplying that amount by the eight days.
The total amount of homework you need to do that week is, 200.

A double day book club is a club that gives double the amount of days in which to read and return literature. Some people find it hard reading a book in a day.
If the terms are 2/10 net 30, that means you receive a 2% discount if you pay the invoice within 10 days, otherwise, the total amount is due in thirty days. So if you pay early, multiply the invoice total by 2% (.02), that is the discount amount to be subtracted from the invoice total.
The amount is equal about .005e693x. More exactly (at least for the next 30 days), y = .005e69314718058x, where x = amount of days and y = amount you would receive on that day. Also, if you start with 2 pennies then the coefficient would change to .01.
If interest does not compound, it will take 100 days to raise it up by 100% (1% per day) If it does, you will double it in just 70 days. Note that in either case it does not depend on the amount invested (in this case 500)
Let's step through the half-life of radon to see how it works. Radon-222 starts at full strength. In four days (its half-life), it is at half strength. In four more days, it is again at half strength (of the half strength) for a total of 1/4 strength. In four more days, it is again half the strength (of the 1/4 strength) for a total of 1/8 strength. In four more days, it is another half life weaker, for a total of 1/16 strength. In 16 days, this isotope of radon has just 1/16th the original radiation.
Oh, what a happy little question! If you were to double one penny every day for 100 days, you would end up with over $6.7 million! Isn't that just amazing? Just imagine all the beautiful things you could create with that much money.
