Environmental scientists often use cost-benefit models to estimate the cost of removing a pollutant from the environment as a function of the percentage of pollutant removed. Suppose a cost benefit function for the cost C (in millions of dollars) of removing x percent of the pollutants from Maple Lake is given by
C(x) = 25x/(100-x)
a. Find the domain and interpret what it means within the text.
b. If federal government wants to remove 90% of the pollutants, how much should the budget be ?
c. If federal government budgets $100 million to clean up the lake, what percent of the pollutants can be removed?
d. If federal government budgets is at least $225 million to clean up the lake, what percent of the pollutants can be removed? (At least means more than 0or equal to)

A literature review of various models, methods and tools used for the evaluation of training effectiveness and its impact on employees' job performance?

Measuring the impact of training on workplace performance and its contribution to organizational results is a matter of great concern for management in all types of organizations. As a result of growing economic pressures, business leaders are becoming more cost conscious and they are more sensitive about the return on training investment. In the current economic downturn, such pressures have further increased. Human resource managers and training professionals have to justify training expenses by providing some evidence about the positive impact of training dollars upon business results. Consequently, the issue of measuring training effectiveness has gained lot of importance over the last few years.

During the past four decades workplace learning & development professionals have done lot of work in the area of evaluating training effectiveness. Dr. Donald Kirkpatrick did some pioneering work in this field and introduced the well known four level evaluation model, which is still widely used in training industry. Later, some other experts also made contribution in this direction and made modification in the existing models.

The attached document provides a literature review on this subject and highlights the research work done in this field. Students of human resource management and training and development will find this material very useful as a reference for their academic assignments.
