3. An investment broker wants to invest up to $20,000. She can purchase type A bond yielding a 10% return and she can purchase a riskier type B bond yielding a 15% return. She wants to invest at least as much in the type A bond as in the type B bond to reduce her risk. The minimum investment for the type A bond is $5,000, and there are only $8,000 worth of type B bonds available. How much should the broker invest in each type of bond to maximize her returns?
12. Zea has a credit limit of $2,000 on her credit card. Each month, she charges about $200 and makes a payment of $125. a. Estimate the number of months that Zea can continue this pattern until she reaches her credit limit. b. Consider that part of the $125 Zea pays each month will be for finance charges. How will the number of months from part a be affected by these charges?
2. Many municipalities offer a variety of fare options for public transportation. This allows high use travelers a choice to pay a lower fare as a benefit of being a high user. The Transit Co. of Blue City, TX has three separate monthly bus fare options to choose from. The first is a standard “per ride" fare of $1.25 per ride. The second allows the rider to purchase a discount card. The cardholder pays $21 at the start of the month plus a fee of S0.50 per ride. Option 3 is a flat fee option where the rider pays $40 for thee month and may ride any bus at no additional cost during the month. Define the variable x to be the number of rides you take each month. Express each option as a function of x. Graph all three functions on the same set of axes. What is the break even number of rides between the options? If you only take 10 rides a month what option should you choose? If you take 40 rides a month what option should you choose? Watch the video posted in the Capstone #1 area involving…
The regional office of the Environmental Protection Agency annually hires second-year law students as summer interns to help the agency prepare court cases. The agency is under a budget and wishes to keep its costs at a minimum. However, hiring student interns is less costly than hiring full-time employees. Accordingly, the agency wishes to hire the maximum number of students without overstaffing. On the average, it takes two interns all summer to research a case. The interns turn their work over to staff attorneys, who prosecute the cases in the fall when the circuit court convenes. The legal staff coordinator has to place his budget request in June of the preceding summer for the number of positions he wishes to maintain. It is therefore impossible for him to know with certainty how many cases will be researched in the following summer. The data from the preceding summers are as follows Year: 1987 1988 1989 1990 1991 1992 1993 1994 1995 1996 Cases: 6…
You are the VP, Advertising for “Yo’ Mama” brand, a fashion label that caters to the young, trendy crowd with an urban, hip-hop image. While your customer base has traditionally been largely African-American, you have recognized a tremendous influx of Hispanic consumers into your market. You are preparing for next week’s annual budget meetings and you have decided to recommend an Hispanic-focused advertising campaign if the average monthly per store sales to Hispanic customers are at least the same as the average monthly per store sales to African-American customers in a sample of typical stores (sales data given below). Using an alpha of .05 and the 5-step hypothesis testing process, what will you recommend? Hint: Think about how many data points you actually have.
For a lifetime life insurance purchased by someone aged 40, some of the following information is provided: • The death benefit is paid at the end of the year of death of $35000 if you die at age 20 year from first contract, $70000 if dies after 20 years of contract. • Premiums with the same amount are paid on average twice a year for a maximum of 20 years as long as they are alive. ä40 = 18,458 60= 14,904 ä50 = 17,025 ä(2) 40:201 = 19,628 ä(2)50:101 = 17,553 20E40 0,36663 10E50 0,60182 i = 0,05 Calculate the benefit reserve at time 10, that is 10V, using the prospective method! =
32. A hardware company sells a lot of low-cost, highvolume products. For one such product, it is equallylikely that annual unit sales will be low or high. Ifsales are low (30,000), the company can sell theproduct for $20 per unit. If sales are high (70,000),a competitor will enter and the company will be ableto sell the product for only $15 per unit. The variablecost per unit has a 20% chance of being $10, a 60%chance of being $11, and a 20% chance of being $12.Annual fixed costs are $20,000.a. Use simulation to estimate the company’s expectedannual profit.b. Find a 95% interval for the company’s annualprofit, that is, an interval such that about 95% ofthe actual profits are inside it.c. Now suppose that annual unit sales, variable cost,and unit price are equal to their respective expectedvalues—that is, there is no uncertainty. Determinethe company’s annual profit for this scenario.d. Can you conclude from the results in parts a and cthat the expected profit from a simulation is…
