Research an Economic Term. The student text describes both commodity money and fiat money. Another term that is used to describe a type of money is representative money. This term is defined differently by different people. Some use this term to only identify a claim on a commodity money (such as a document that represents or "stands in place of" actual gold). Others use this term to denote any money where the face value of the money (the $5 or$10 say, written on the face (front) of the money) represents a greater value than the value of the material. Go online and find examples of people using this term. Then, using your research to support your view, describe representative money in your own words

A commonly used IQ test is scaled to have a mean of 100 and a standard deviation of $\sigma=15$. A school counselor was curious about the average IQ of the students in her school and took a random sample of fifty students' IQ scores. The average of these was $\bar{y}=107.9$. Find a 95% confidence interval for the student IQ in the school.

Collaborate to Classify a Market. Working in a small group, collaborate to research the U.S. railroad Industry just after the turn of the 20th century (the early 1900 s). As part of your research, respond to the following questions. How many different railroad companies existed during this time period? How many different people or organizations owned them? Did people have a choice of which railroads to use? When you have finished your research, research, review the definitions of perfectly competitive, monopolistic, monopolistic competitive, and oligopolistic markets in your book Work with your group to answer this question: Which kind of market was the railroad industry in the early 1900s, and how do you know? As a group, brainstorm to think of a current market of the same type. Compare and contrast it with the railroad industry of the early 1900s and then write a short report summarizing your findings.

A software company that installs systems for inventory control using RFID technology spent $600,000 per year for the past 3 years in developing their latest product. The company optimistically hopes to recover its investment in 5 years on a single contract beginning immediately (year 0). The company is negotiating a contract that will pay$250,000 now and a to-beagreed-upon annual increase of a constant amount each year through year 5. How much must the income increase (an arithmetic gradient) each year, if the company wants to realize a return of 15% per year?

Determine each value. a. 7% of 26 b. 28% of 90
