Any company’s assets are either financed by its debt or by its equity. The Weighted Average Cost of Capital is the average costs of these sources of financing‚ each of which is weighted by its respective use in the given situation. By taking the weighted average‚ we can see how much interest the company has to pay for every dollar it finances. Basically‚ the WACC is the minimum required return that the company must earn to satisfy its creditors‚ owners‚ and other providers of capital‚ or they will

Introduction and background We are conducting an analysis of Marriott Corporation for calculating the hurdle rates at each of the firm ’s three divisions--lodging division‚ restaurant division and contract service division. Marriott uses Weighted Average Cost of Capital (WACC) as the hurdle rate‚ and use it to discount the appropriate cash flows when evaluate an investment project. Our goal is to determine the WACC at every division base on the information that the case has provided. First

the numerators are the same in one row. Each numerator after 1 is the sum of 1+2+…+n (n=row number) which forms an arithmetic series. For example: When n=3‚ the numerator will be t3=1+2+3=6. Table 1: Row Number and Numerator Row Number Numerator Investigation 1 1 t1=1 2 3 t2=1+2 3 6 t3=1+2+3 4 10 t4=1+2+3+4 5 15 t5=1+2+3+4+5 Therefore‚ according to this arithmetic series tn=1+2+3+…+n‚ (n=row number)‚ we can find out the numerator of the sixth row is t6=1+2+3+4+5+6=21 Part 2:

used for both graphs‚ they would look as follows: Example 2: ABC.com presented that the average blood sugar level before meals for Americans is 142 mg/dL but did not specify how the average was calculated. What they did not share was that the mean‚ or arithmetic average‚ was calculated from a sample size of only four people. Of these four people‚ all of the blood sugar levels (before meals) were in normal ranges and one person had a blood sugar level of 240 mg/dL‚ causing the entire group’s average to be skewed
