Money problems

Ok, so I've looked at the figures - and something's gone seriously wrong.
These are the reciept totals I've added up.

Ad team
budget: $50 + 80 (from construction team) = $130
23.37
17.61 = $63.48 (expense)
22.50

Construction team
Budget: $250 – 80 = $170
28.50
43.76 (paid by Syd)
18.15
11.35
29.02 = $169.95 (expense)
9.12
20.76
9.29

Tech team
budget: $80
?


total expense: $233.43 +
total change received: $75.58 = 309.01
total money collected: $380.00

**MONEY UNACCOUNTED FOR: $70.99

obviously this is a big problem. tech team, I still haven't gotten the breakdown of your expenses.
I'm thinking there was some money exchanges between groups that no one told me about.
Can anyone explain what happened here?

Thanks,
Amy
