The daily costC(in dollars) of removing pollution from the smokestack of a coal-fired electric power plant is related to the percent of pollution p being removed according to the equation 100C - Cp = 10,500.

1. Solve this equation for C to write the daily cost as a function of p, the percent of pollution removed.
2. What is the daily cost of removing 50% of the pollution?
3. Why would this company probably resist removing 99% of the pollution?
