Let's apply what you have learned from the lesson. The concentration (C) of a given substance in a mixture is the ratio of the amount of substance to the total quantity. In symbols, 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: a. How much orange juice do you begin with? Write an expression for the amount of orange juice present after x ounces has been added. b. Write an expression for the total amount of punch present after x ounces has been added. c. Using the answers in (a) and (b), write a rational function defining the pineapple juice concentration as a function of x.

Question
Let's apply what you have learned from the lesson.
The concentration (C) of a given substance in a mixture is the ratio of the
amount of substance to the total quantity. In symbols,
S
C =-
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:
a. How much orange juice do you begin with? Write an expression for
the amount of orange juice present after x ounces has been added.
b. Write an expression for the total amount of punch present after x
ounces has been added.
c. Using the answers in (a) and (b), write a rational function defining
the pineapple juice concentration as a function of x.
d. Give the x and y - intercepts of the rational function,
e. What is the equation of the vertical asymptote and of the horizontal
asymptote?
