Combined bet with Asian odds

[guty]

 

I have a question

Asian odds divide half of the bet
Betting with the Asian Handicap on total goals (also called 'Asian Totals') is similar to the over/under bet, except that with Asian Totals you can get a higher return: you receive 50% of your bet if you 'half lose' ' or 50% of the profit if you 'half win'.

Now, how is this type of bet considered in combined?
For example

In this example a bet of

QUOTE: 3.59 
BET: US$2.5

How would the supposed half be divided?
And how would the calculation be in this case, if two are lost? How much should the fee and the value bet be? What would be the formula to know this settlement?
