Date released: July 18th, 2001.
Date rewarded: July 24th, 2001.

Heermeedjet the Meerca has 5,000 Neopoints in his pocket (after successfully breaking into somebody's Neohome). He has a go on the Wheel of Excitement and then increases the amount of money he has by 20%. He then takes 20% of his money and spends it on Neggs.

Heermeedjet then puts the rest of the money in the National Neopian Bank, and earns 1% interest every day (daily interest is rounded down) for 10 days. After 10 days he gets bored and puts the all the money on a Poogle at 3:1 odds and wins.

Heermeedjet starts off with 5,000 NP.
He gains 20% through the Wheel of Excitement, so he has:

5,000 * 120% = 6,000

He spends 20% on Neggs, so he has left:

6,000 * 80% = 4,800

He puts the NP into bank, and earn interest everyday. Here is what he earns for 10 days (interests are rounded down):

1. Day 1: 1% of 4,800 = 48. He then has 4,848 NPs.
2. Day 2: 1% of 4,848 = 48. He then has 4,896 NPs.
3. Day 3: 1% of 4,896 = 48. He then has 4,944 NPs.
4. Day 4: 1% of 4,944 = 49. He then has 4,993 NPs.
5. Day 5: 1% of 4,993 = 49. He then has 5,042 NPs.
6. Day 6: 1% of 5,042 = 50. He then has 5,092 NPs.
7. Day 7: 1% of 5,092 = 50. He then has 5,142 NPs.
8. Day 8: 1% of 5,142 = 51. He then has 5,193 NPs.
9. Day 9: 1% of 5,193 = 51. He then has 5,244 NPs.
10. Day 10: 1% of 5,244 = 52. He then has 5,296 NPs.

He puts all NPs into Poogle Race with odd 3:1 and wins (hence he quadruples his NPs). So he has:

5,296 * 4 = 21,184

Heermeedjet has 21,184 NPs left.
