Imagine your family agreed to give you some pocket money every day for a month! You can choose from the following options:

  1. £10 every day
  2. £3 on the first day, £3.50 on the second, £4 on the third, and so on, increasing by 50p per day
  3. 1p on the first day, 2p on the second, 4p on the third, and so on, doubling each day.

Without doing any working out, which one would you choose, and why?

In a month with 31 days, how much money would you have by the end of the month, under each system? You may wish to explore using a spreadsheet…

In which months would option 1 be better than option 2?
If your family stopped your pocket money on day 8, which option would give you the most?
On which day of the month does option 3 become the most fruitful?
If you chose option 3, how many days would it be before you became a millionaire?
