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 get:

2\cdot 9=18\\\\\\9\cdot 8000=72000

Therefore, we conclude that is needed 72000 salmon eggs  to produce 18 adult salmon.
