In that case I make it:I think that's what I said only backwards! No money spent, Halvor is busy leveling his new floors.
Money coming in:
ATT 59*£3.50 = £206.50
iKon 59*£1.00 = £59.00
Hone 42*£2.00+£2.00 = £86.00
Tips: £21.77 (or wherever that money comes from)
Total: £351.50 + 21.77 = £373.27
Money out: at most £155.00 for the ATT
Left for the charity: at least £373.27 - £155.00 = £218.27 (plus 2 extra quid if Mr BigMem pays for a Hone ticket)
Why not wait until halvor has a level floor, pay for the ATT he picks, then give the remainder to the TSR charity?
