Answer:
Either you quit trying and lose $800 sunk, or you spend $800 for $1,600 total in which the Net from the sale of $1,000 would results in a loss of $600. That means it will be of good to lose $600 than $800.
Explanation:
Since $800 has been spent which means Spending up to an additional $1,000 is still reasonable, but a condition in which you know that the deal will definitely go through.
Secondly since you have already sunk $800, and you know that spending an additional $800 would guarantee it, you can do one among this two options which are either you stop trying and lose the $800 sunk, or you the spend $800 for $1,600($1,000+$600) total in which the Net from the sale of $1,000 would results in a loss of $600($1,000-$800=200,$800-$200=$600). That means it will be of good to lose $600 than $800.

All of the above are possible.
Explanation:
Discussions here center on equilibrium of an economy in a long run, and here after the government activities, their is a decline in dollar value; therefore in the short run, the price level and real GDP will both rise in as much as the price level and real GDP will also both fall. It is also gathered that neither the price leave nor real GDP will change.
The transition from the short run to the long run may be done by considering some short run equilibrium that is also a long run equilibrium as to supply and demand, then comparing that state against a new short run and long run equilibrium state from a change that disturbs equilibrium, say in the sales tax rate, tracing out the short run adjustment first, then the long run adjustment.
