OK
bet 2:
we lost in bet 1 to make 100 and the cost was in this case 55
we still want to make our 100 for the day.
So now we need to make 155

1.90 = 123 units
3.50 = 67 units
23.50 = 11 units
total units = 201

4 won and paid 4.00, return
67 multiplied by 4 = 268

less 201 cost, profit, 67

had the fav won,if it paid 1.90 * 123
this equates to : 233.70
less cost of 201.00 ,profit 32.70
