A power company burns coal to generate electricity. The cost C x (in $1000 ) to remove x % of the air pollutants is given by C x = 600 x 100 − x a Compute the cost to remove 25 % of the air pollutants. b. Determine the cost to remove 50 % , 75 % , and 90 % of the air pollutants. c If the power Company budgets $ 1.4 million for pollution control, what percentage of the air pollutants can be removed?

During a nationwide program to immunize the population against a new strain of the flu, public health officials determined that the cost of inoculating x% of the susceptible population would be approximately C (x) = 1.85 x / 100-x Suppose 17 million dollars are available for providing immunization.What percentage of the susceptible population will not receive immunization?
A landscaping company is hired to mow the grass for several large properties. The total area of the properties combined is 1,350 acres. The rate at which one person can mow is as follows: Ŷ = -1.8X + 1350Where X is the number of hours and Ŷ represents the number of acres left to mow.a. How many acres will be left to mow after 40 hours of work by one person?b. How many acres will be left to mow after 100 hours of work by one person? (now you see why you need a large crew to mow many acres!)
(b) During a nationwide program to immunize the population against a new strain of the flu,public health officials determined that the cost of inoculating x% of the susceptible populationwould be approximately C(x) =1.85x million dollars. 100 − x(iii) Suppose 17 million dollars are available for providing immunization. What percentageof the susceptible population will not receive immunization?
(iv) If money was not a problem will they be able to providing immunization to the entiresusceptible population?
