...double taxation to shareholders on distributed earnings and dividends. Some advantages include: limited liability, ease of transferability, ability to raise capital, and unlimited life. When a business is started, most take the form of a sole proprietorship or partnership because of the relative simplicity of starting these forms of businesses. 2. To maximize the current market value (share price) of the equity of the firm (whether it’s publicly traded or not). 3. In the corporate form of ownership, the shareholders are the owners of the firm. The shareholders elect the directors of the corporation, who in turn appoint the firm’s management. This separation of ownership from control in the corporate form of organization is what causes agency problems to exist. Management may act in its own or someone else’s best interests, rather than those of the shareholders. If such events occur, they may contradict the goal of maximizing the share price of the equity of the firm. 4. Such organizations frequently pursue social or political missions, so many different goals are conceivable. One goal that is often cited is revenue minimization; i.e., provide whatever goods and services are offered at the lowest possible cost to society. A better approach might be to observe that even a not-for-profit business has equity. Thus, one answer is that the appropriate goal is to maximize the value of the equity. 5. Presumably, the current stock value reflects the risk, timing, and magnitude of......

...Question 2 (10 points) 2. Two people, Ella and Jane, decide to start saving for retirement. Ella decides to invest $4000 a year into an annuity at the age of 25. At the age of 35 she stops making investments and just leaves the money there. Jane on the other hand, decides to start investing $4000 a year at the age of 40 and invests that money for every year thereafter. Assuming both retire at 70, and that the interest rate both get on their investments is 10% (compounded annually) who has the most money in their account at age 70? Explain why you pick the answer you pick. Have to caculate the future value for both Ella and Jane. The RATE you have to use for this question is found on Tables 14-1 and 13-1 so use table method. Table method: for ella there are two caluclations. First find future value of her annuity (from 25 to 35) using table 14-1. The amount becomse the present value for finding the future value (from 35 to 0) using table 13-1. Jane only has one calculation. Find the future value of her annuity (40 to 70) using table 14-1.

...INTRODUCTION Refer to the American Heritage Dictionary of the English Language, mathematics is the study of the measurement, properties, and relationships of quantities and sets, using numbers and symbols. Mathematical had been invented early in ancient Egypt, Mesopotamia and ancient India. Until today, development of mathematics still ongoing. Mathematics has become our indispensable part of daily life. Besides that, mathematics has been incorporated into the field of education. Today mathematics has been widely used in various fields such as science, medicine, engineering and business. Leonardo Da Vinci was an Italian polymath. His field of interest included invention, painting, architecture, science, music, mathematics, engineering, literature, anatomy, geology, astronomy, writing, history, and so on. He was well-known as a painter. Mona Lisa is one of his famous works. However, he also a famous mathematician in the world. He has a great contributions for the history of mathematic. Leonardo da Vinci thought that mathematics was an essential tool for painting. He had explored the laws of geometric between hexahedron, cylinder, and sphere area. He was the first person using the symbol of plus (+) and minus (-) in mathematics. Grace Hopper was a representative of a modern mathematician. She had great contributions on mathematics because mathematics was her favourite subject since childhood. She obtained her master’s degree in mathematics in 1930 and received her PhD in......

...Simple interest is the interest that is computed on the original principal only. If I denotes the interest on a principal P (in dollars) at an interest rate of r per year for t years, then we have I = Prt The accumulated amount A, the sum of the principal and interest after t years is given by and is a linear function of t. A= P + I = P + Prt = P(1 + rt) A bank pays simple interest at the rate of 8% per year for certain deposits. a. If a customer deposits $1000 and makes no withdrawals for 3 years, what is the total amount on deposit at the end of three years? P = 1000, r = 0.08, and t = 3 A=P(I+rt)=1000[1+(0.08)(3)]=1240 or $1240 b. What is the interest earned in that period? I=Prt=1000(0.08)(3)=240 or $240. Compound interest Frequently, interest earned is periodically added to the principal and thereafter earns interest itself at the same rate. This is called compound interest. Suppose $1000 (the principal) is deposited in a bank for a term of 3 years, earning interest at the rate of 8% per year compounded annually. Using the simple interest formula we see that the accumulated amount A1 = P (1+rt) =1000[1+0.08(1)] =1080 These observations suggest the following general rule: If P dollars are invested over a term of t years earning interest at the rate of r per year compounded annually, then the accumulated amount is This formula is derived under the assumption that interest was compounded annually. In practice, however, interest is usually compounded......
