PROBLEM 16-12 Financial Ratios for Common Stockholders [L02] Refer to the financial statements and other data in Problem 16-11. Assume that you have just inherited several hundred shares of Modem Building Supply stock. Not being acquainted with the company, you decide to do some analytical work before making a decision about whether to retain or sell the stock you have inherited. Required: 1. You decide first to assess the well-being of the common stockholders. For both this year and last year, compute the following: a. The earnings per share. b. The dividend yield ratio for common stock. The company's common stock is currently sell- C. ing for $45 per share; last year it sold for $36 per share. The dividend payout ratio for common stock. d. The price-earnings ratio. How do investors regard Modern Building Supply as compared to other companies in the industry? Explain e. The book value per share of common stock. Does the difference between market value and book value suggest that the…
Consider again the scenario described in Problem 4. The Center for Business Analytics is considering a refund policy for no-shows. No refund would be given for members who do not attend, but nonmembers who do not attend will be refunded 50 percent of the price. Extend the model you developed in Problem 4 for the Business Intelligence Symposium to account for the fact that, historically, 25 percent of members who registered do not show and 10 percent of registered nonmembers do not attend. The Center pays the caterer for breakfast and lunch based on the number of registrants (not the number of attendees). However, the Center pays for parking only for those who attend.What is the profit if each corporate member registers their full allotment of tickets and 127 nonmembers register? Use a two-way data table to show how profit changes as a function of number of registered nonmembers and the no-show percentage of nonmembers. Vary the number of nonmember registrants from 80 to 160 in…
CASE PROBLEm 2 : AFRICAN ELEPHANT POPULATIONS Although millions of elephants once roamed across Africa, by the mid-1980s elephant populations in African nations had been devastated by poaching. Elephants are important to African ecosystems. In tropical forests, elephants create clearings in the canopy that encourage new tree growth. In savannas, elephants reduce bush cover to create an environment that is favorable to browsing and grazing animals. In addition, the seedsof many plant species depend on passing through an elephant’s digestive tract before germination. The status of the elephant now varies greatly across the continent. In some nations, strong measures have been taken to effectively protect elephant populations; for example, Kenya has destroyed over five tons of elephant ivory confiscated from poachers in an attempt to deter the growth of illegal ivory trade (Associated Press, July 20, 2011). In other nations the elephant populations remain in danger due to poaching for…
Problem 3: car-planes and city size. Consider a regional economy with 12 million workers and an urban utility curve of u(n) = 15 + 12n − 2n2, where n is the number of workers in millions. Initially the region has four cities, each of the same size. Suppose city A introduces carplanes to replace regular cars for commuting and its urban utility function is u(n) = 15 + 12n − n2. Predict the effect of the carplane on the equilibrium distribution of population between cities the equilibrium utility level and regional utility.

Problem 3. Suppose a test for detecting a certain rare disease has been perfected that is capable of discovering the disease in 97% of all afflicted individuals. Suppose further that when it is tried on healthy individuals, 5% of them are incorrectly diagnosed as having the disease. Finally, suppose that when it is tried on individuals who have certain other milder diseases, 10% of them are incorrectly diagnosed. It is known that the percentages of individuals of the three types being considered here in the populations at large are 1%, 96%, and 3%, respectively. Calculate the probability that an individual, selected at random from the population at large and tested for the rare disease, actually has the disease if the test indicates he is so afflicted.
Rework problem 15 in section 2 of Chapter 5 of your textbook about the growing suburb and the declining city using the following data: Assume that the suburb has a population of 808000 and is growing at a rate of 3000 per year. Assume that the city has a populatior of 1060000 and is declining at a rate of 15000 per year. In how many years will the populations of the suburb and the city be equal? What will the populations be when they are equal?

Case. 15.1. Ski Jacket Production. Egress, Inc., is a small company that designs, produces, and sells ski jackets and other coats. The creative design team has labored for weeks over its new design for the coming winter season. It is now time to decide how many ski jackets to produce in this production run. Because of the lead times involved, no other production runs will be possible during the season. Predicting ski jacket sales months in advance of the selling season can be quite tricky. Egress has been in operation for only three years, and its ski jacket designs were quite successful in two of those years. Based on realized sales from the last three years, current economic conditions, and professional judgment, 12 Egress employees have independently estimated demand for their new design for the upcoming season. Their estimates are listed in Table 15.2 To assist in the decision on the number of units for the production run, management has gathered the data in Table 15.3. Note that S…
