The number of milligrams per liter of POC were in the bay when the zebra mussels were first introduced is 0.4 milligrams per liter.
The expression is an equation
<h3>What is an equation?</h3>
An equation is a mathematical expression that shows the relationship between two quantities.
<h3>How to find how many milligrams per liter of POC were in the bay when the zebra mussels were first introduced?</h3>
Now, since the concentration, c, of POC (in milligrams per liter) remaining in a particular bay m months after the introduction of a population of zebra mussels can be estimated using the following equation c = 0.4 - 0.9m
Now, to find how many milligrams per liter of POC were in the bay when the zebra mussels were first introduced, this would be the initial value of m at 0 months.
So, substituting m = 0 into the equation, we have
c = 0.4 - 0.9m
c = 0.4 - 0.9(0)
c = 0.4 - 0
c = 0.4 milligrams per liter
So, the number of milligrams per liter of POC were in the bay when the zebra mussels were first introduced is 0.4 milligrams per liter.
