Darah has 200 milliliters of a salt and water solution that is 12% salt. She begins to add a salt and water solution
that is 5% salt to the 12% solution. The percent of salt in Darah's combined solution when x milliliters of the 5%
solution have been added can be modeled by Cwx) =
2,400 + 5x
200 + x
Two different tables of values for C(x) are given below. Use the tables to answer the questions that follow.

Part A: 2 points
Is this function increasing or decreasing? What does this mean in the context of the problem?
Part B: 2 points
What is the horizontal asymptote of the function? Interpret the meaning of the asymptote in
the context of the problem.

  A) decreasing. Salt concentration is being reduced.

  B) 5%. The more 5% solution that is added, the closer the mixture becomes to 5%.

Step-by-step explanation:

A) Increasing values of x result in decreasing values of C(x), so the function is decreasing.

This means that when a lower concentration of salt solution is added to one of higher concentration, the result is a decrease in the concentration of salt in the mixture.

__

B) As x gets very large, C(x) approaches 5. The horizontal asymptote is C=5.

In the context of the problem, it means that as the solution contains more and more 5% brine, the concentration of salt in the mix approaches 5%.
