Let z represent the number of large drinks consumed, f(x) represent
amount spent on the $5.75 drinks, and g(x) represent the amount spent on
the commemorative drink containers.
Part A: Write expressions for f(x) and g(x).
Part B: For what value of x does f(x) = g(x)?
Part C: What does it mean for f(x) = g(x)?
Part D: Write a reasonable domain for g(x).
Part E: Explain when it would be a better deal to purchase the
commemorative container.
