The concentration (C) of a given substance in a mixture is the ratio of the amount of substance to the total quantity. In symbols, C = S where C is the concentration, S is the amount of substance, and T is the total quantity. If 8 ounces of punch contains 4 ounces of pure orange juice, the concentration of orange juice in the punch is 4/8 or 50%. The punch is 50% orange juice. Consider the problem where we begin that 8 ounces of punch that is 50% orange juice and want to write a function that gives the orange juice concentration after x ounces of pure orange juice are added. Questions: 1. How much orange juice do you begin with? Write an expression for the amount of orange juice present after x ounces has been added. 2. Write an expression for the total amount of punch present after x ounces has been added. 3. Using the answers in (a) and (b), write a rational function defining the pineapple juice concentration as a function of x. 4. Give the x and y - intercepts of the rational function. 5. What is the equation of the vertical asymptote and of the horizontal asymptote?

Question

Read and answer the 3, 4, and 5 questions below. Show the solutions and final answers.

The concentration (C) of a given substance in a mixture is the ratio of the
amount of substance to the total quantity. In symbols,
C = S
Q
where C is the concentration, S is the amount of substance, and T is the total
quantity. If 8 ounces of punch contains 4 ounces of pure orange juice, the
concentration of orange juice in the punch is 4/8 or 50%. The punch is 50%
orange juice. Consider the problem where we begin that 8 ounces of punch that
is 50% orange juice and want to write a function that gives the orange juice
concentration after x ounces of pure orange juice are added.
Questions:
1. How much orange juice do you begin with? Write an expression for the
amount of orange juice present after x ounces has been added.
2. Write an expression for the total amount of punch present after x ounces
has been added.
3. Using the answers in (a) and (b), write a rational function defining the
pineapple juice concentration as a function of x.
4. Give the x and y - intercepts of the rational function.
5. What is the equation of the vertical asymptote and of the horizontal
asymptote?
