Hedge/Dutch Formulas
In a PPM archive article, they have the formula for a dutch/hedge calculations.
Formula A
The way the formula is constructed, it uses the ( spend the whole $20.00) on your 3 selected runners.
That's OK, I have no issues about it.
Formula B
I need the "reverse" method, where it's, make a profit of $20.00 on your selected 3 runners.
The Formula A as wriiten from a PPM article is:

Let’s look at Dutching calculations.Let’s say we are going to Dutch three horses in a race.
Horse A = 3.5 (5/2)
Horse B = 4.00 (3/1)
Horse C = 5.00 (4/1)
Next, you convert the odds to their percentage chance by dividing into 100:
Horse A = 28.57 per cent (100 divided by 3.5 equals 28.57)
Horse B = 25 per cent (100 divided by 4 equals 25)
Horse C = 20 per cent (100 divided by 5.00 equals 20)
The next step is to add the percentages together:
28.57 + 25 + 20 = 73.57 per cent
So there should be (all things being equal) that we have a 73.57 per cent chance of one of our runners winning the race.
Now to find out what to bet on each runner: You divide each horse’s individual percentage by the overall percentage figure – then multiply by the total amount you want to stake on the event ($20 in this example).
Horse A 28.57 / 73.57 x 20 = 7.76
Horse B = 25 / 73.57 x 20 = 6.80
Horse C = 20 / 73.57 x 20 = 5.44
Total stake 7.76 + 6.80 + 5.44 = 20

So what would be the "reverse" to "make $20.00 profit after total bet cost" formula be, using the same part where it says,
