Scenario Much like the decision to start a business, the decision to attend college is fraught with risk; however, the risk of entering the job market with only a high school diploma is just as great. As the U.S. transformed from a manufacturing-based economy to an economy based on knowledge, high school graduates are often unable to obtain the number of high-paying jobs that were once available. College graduates earn more-some suggest as a much as 60% more over a lifetime-than those without a college degree, and have a lower divorce rate, lower blood pressure and stress levels, and higher rates of job stability and satisfaction. However, a college education may not be the right choice for some. There may be a glut of college-educated workers in our workforce, and many careers, including those in cosmetology, do not require a college degree. The U.S. Department of Labor projects jobs for hairdressers, hairstylists, cosmetologists, and skin care specialists to grow 9-17% through the year 2014. In 1970, fewer than 1% of taxi drivers and 2% of firefighters had college degrees, but today more than 15% of workers in both jobs do. As the costs of a college education skyrockets, student loan debt closely follows. Since 2003, the student loan debt held by Americans has quadrupled, growing from $241 billion to $1.03 trillion, rising 14% per year. The decision to attend college is risky. It might pay off handsomely, or it could sink a student's future. Some suggest that college graduates eam more than high school graduates over the course of a lifetime.

Cholesterol Cholesterol in human blood is necessary, but too much can lead to health problems. There are three main types of cholesterol: HDL (high-density lipoproteins), LDL (low-density lipoproteins), and VLDL (very low-density lipoproteins). HDL is considered “good” cholesterol; LDL and VLDL are considered “bad” cholesterol. A standard fasting cholesterol blood test measures total cholesterol, HDL cholesterol, and triglycerides. These numbers are used to estimate LDL and VLDL, which are difficult to measure directly. Your doctor recommends that your combined LDL/VLDL cholesterol level be less than 130 milligrams per deciliter, your HDL cholesterol level be at least 60 milligrams per deciliter, and your total cholesterol level be no more than 200 milligrams per deciliter. (a) Write a system of linear inequalities for the recommended cholesterol levels. Let x represent the HDL cholesterol level, and let y represent the combined LDL VLDL cholesterol level. (b) Graph the system of inequalities from part (a). Label any vertices of the solution region. (c) Is the following set of cholesterol levels within the recommendations? Explain. LDL/VLDL: 120 milligrams per deciliter HDL: 90 milligrams per deciliter Total: 210 milligrams per deciliter (d) Give an example of cholesterol levels in which the LDL/VLDL cholesterol level is too high but the HDL cholesterol level is acceptable. (e) Another recommendation is that the ratio of total cholesterol to HDL cholesterol be less than 4 (that is, less than 4 to 1). Identify a point in the solution region from part (b) that meets this recommendation, and explain why it meets the recommendation.

Use this data for the exercises that follow: In 2013, there were roughly 317 million citizens in the United States, and about 40 million were elderly (aged 65 and over).[34] 60. It is predicted that by 2030, one in five U.S. citizens will be elderly. How much greater will the chances of meeting an elderly person be at that time? What policy changes do you foresee if these statistics hold true?

If during the following year it is predicted that each comedy skit will generate 30 thousand and each musical number 20 thousand, find the maximum income for the year. A television program director must schedule comedy skits and musical numbers for prime-time variety shows. Each comedy skit requires 2 hours of rehearsal time, costs 3000, and brings in 20,000 from the shows sponsors. Each musical number requires 1 hour of rehearsal time, costs 6000, and generates 12,000. If 250 hours are available for rehearsal and 600,000 is budgeted for comedy and music, how many segments of each type should be produced to maximize income? Find the maximum income.
