the total profit the farmer can earn is 5000*x + 3000*y. let p = total profit that can be earned. your equation for profit becomes: p = 5000x + 3000y that’s your objective function. it’s what you want to maximize the constraints are: number of acres has to be greater than or equal to 0. number of acres has to be less than or equal to 8. amount of pesticide has to be less than or equal to 10. your constraint equations are: x >= 0 y >= 0 x + y <= 8 2x + y <= 10 to graph these equations‚ solve for

An Introduction to Linear Programming Steven J. Miller∗ March 31‚ 2007 Mathematics Department Brown University 151 Thayer Street Providence‚ RI 02912 Abstract We describe Linear Programming‚ an important generalization of Linear Algebra. Linear Programming is used to successfully model numerous real world situations‚ ranging from scheduling airline routes to shipping oil from refineries to cities to finding inexpensive diets capable of meeting the minimum daily requirements.

THE PHILLIPS CURVE The short-run relationship between inflation and unemployment is often called the Phillips curve. In 1958‚ economist A. W. Phillips published an article in the British journal Economica that would make him famous. The article was titled “The Relationship between Unemployment and the Rate of Change of Money Wages in the United Kingdom‚ 1861–1957.” In it‚ Phillips showed a negative correlation between the rate of unemployment and the rate of inflation. That is‚ Phillips showed

Learning curve in psychology and economics The first person to describe the learning curve was Hermann Ebbinghaus in 1885. He found that the time required to memorize a nonsense word increased sharply as the number of syllables increased.[1] Psychologist‚ Arthur Bills gave a more detailed description of learning curves in 1934. He also discussed the properties of different types of learning curves‚ such as negative acceleration‚ positive acceleration‚ plateaus‚ and ogive curves.[2] In 1936‚ Theodore
