For each month
1. £310-In this case I times 31 and 10 beacause they are given £10 each day for 31 days

2. £344-here, I worked out that the numbers (e.g. 3&4=7 and 5&6=11 and if you see 11-7 =4.) This also occurs with the other sets (e.g. 3.50+4.50=8 and 5.50+6.50=12. 12-8=4). Both patterns are going up in fours in pairs. So going between a pound and a pound and fifty pence until you get to thirty one. When I got to 31 results I again added them up and got the result of £344.

3. £21474831.35- I doubled the numbers until I had 31 results. I then added these results and got the answer above. However, the result could be inaccurate by a few numbers and in this case the answer could may well be
£21474836.48
