Work the following problem. (See Example.)

The owners of a parking lot have determined that their weekly revenue and cost in dollars are given by R(x) = 80x and C(x) = 50x + 2400, where x is the number of long-term parkers.

(a) Find the break-even point.

---

(b) Graph R(x) and C(x) on the same axes.

---

(c) From the graph, estimate the revenue and cost when there are 60 long-term parkers.

Example

Find the break-even point for the company in Example 6.
