The cost to reserve a banquet hall is $500. The catering cost per guest is $17.50 for the first 40 guests and $14.75 for each additional guest.
a. Write a piecewise function describing the cost C
of the reunion.
b. Use a graphing calculator to graph the function


Sagot :

The piecewise function describing the cost C of the reunion are C(x) = 500 + 17.5x, where x <= 40 and  C(x) = 1200 + 14.75(x - 40), where x > 40

Write a piecewise function describing the cost C of the reunion.

The given parameters are:

Reserve = $500

Cost per guest = $17.50 for the first 40 guests

Cost per guest = $14.75 for each additional guest

The above means that

C(x) = 500 + 17.5x, where x <= 40

C(x) = 500 + 17.5 * 40 + 14.75(x - 40), where x > 40

Next, we evaluate the functions

This gives

C(x) = 500 + 17.5x, where x <= 40

C(x) = 1200 + 14.75(x - 40), where x > 40

Use a graphing calculator to graph the function

To do this, we simply plot each function with its domain
