up to 100 tickets at a time.

a. Write a function C(t) that models the cost (C) of attending the fair for four people

and purchasing t tickets.

b. Explain why this function must be a piecewise-defined function.

c. Graph the function.

d. Write the real-world domain and range of this function.

e. Is the flat cost of 100 tickets a good deal? How much money will it save you?

Explain how you know.

f. You and your family of four estimates that you need 120 tickets to enjoy
