just have a whole heap on there, they used to compound. For example if you got $10 per every 3 minutes +10% per Stock exchange X 30. I think that was how it worked, I used to get heaps of cash that way. But as I said I had over 30 stock exchanges and changed all my business skins to offices.
Hope this makes sense
I've poached this from another forum but I think it helps explain the 'stacking' of wonders. Old (before the recent update) Vs New (after you've updated). I think the lesson is, if you haven't updated yet then don't, wait until you've saved up enought coins that you're happy with before updating. Ok so the explination is:
OLD MATH
100 + 20% = 120 + 20% = 144 + 20% = 172.8 + 20% = 207.36, etc. .........
Office business:
Zero Stock Exchanges - 100 coins for 3 minute job = 100
5 Stock Exchanges - 100 coins for 3 minute job = 248.83
10 Stock Exchanges - 100 coins for 3 minute job = 619.17
50 Stock Exchanges - 100 coins for 3 minute job = 758,369
60 Stock Exchanges - 100 coins for 3 minute job = 4,695,626
70 Stock Exchanges - 100 coins for 3 minute job = 29,074,079
NEW MATH:
Office business:
Zero Stock Exchanges - 100 coins for 3 minute job = 100
5 Stock Exchanges - 100 coins for 3 minute job = 200
10 Stock Exchanges - 100 coins for 3 minute job = 300
50 Stock Exchanges - 100 coins for 3 minute job = 1,100
60 Stock Exchanges - 100 coins for 3 minute job = 1,300
70 Stock Exchanges - 100 coins for 3 minute job = 1,500
