A cost-benefit function C computes the cost, in millions of dollars, of implementing a city recycling project where x percent of the citizens participate, where. C(x)=x/100-x
a) Graph C using the window settings of [0,100,10] by [0,10,1]. Interpret the graph as x approaches 100.
b) If 75 percent participation is expected, determine the cost for the city recycling project.
c) The city plans to spend $5 million on this project. Estimate the percentage of participation that can be expected.
