Answer
Therefore, we conclude that is needed 72000 salmon eggs to produce 18 adult salmon.
'Step-by-step explanation'
We know that scientists study ways to increase the population of wild salmon. We know that for every 8,000 eggs, only 2 adults may survive.
We calculate how many salmon eggs may be needed to produce 18 adult salmon.
Therefore, we conclude that is needed 72000 salmon eggs to produce 18 adult salmon.
