You simply set up 8 <text> elements, each displaying a different amount of money. Have participants click on one of the <text> elements and subtract the selected amount from their total:
<values>
/ total = 1000
/ amount1 = 10
/ amount2 = 25
</values>
<block myblock>
/ trials = [1-4=allocate]
</block>
<trial allocate>
/ ontrialend = [if (trial.allocate.response=="amount1") values.total-=values.amount1]
/ ontrialend = [if (trial.allocate.response=="amount2") values.total-=values.amount2]
/ stimulusframes = [1=stimulus, amount1, amount2]
/ validresponse = (amount1, amount2)
/ inputdevice = mouse
/ branch = [trial.showmoneyleft]
</trial>
<trial showmoneyleft>
/ stimulusframes = [1=total]
/ validresponse = (0)
/ trialduration = 1000
/ recorddata = false
</trial>
<text stimulus>
/ items = ("A", "B", "C", "D")
</text>
<text amount1>
/ items = ("<%values.amount1%>$")
/ txbgcolor = grey
/ size = (5%, 0.05px*display.width)
/ position = (40%, 75%)
/ vjustify = center
</text>
<text amount2>
/ items = ("<%values.amount2%>$")
/ txbgcolor = grey
/ size = (5%, 0.05px*display.width)
/ position = (60%, 75%)
/ vjustify = center
</text>
<text total>
/ items = ("You still have <%values.total%>$")
/ position = (50%, 50%)
</text>
