Suppose the real risk-free rate is 4.20%, the average expected future inflation rate is 3.10%, and a maturity risk premium of 0.10% per year to maturity applies, i. e., MRP = 0.10%(t), where t is the number of years to maturity, hence the pure expectations theory is NOT valid. What rate of return would you expect on a 4-year Treasury security? Disregard cross-product terms, i. e., if averaging is required, use the arithmetic average.
a. 6.60%
b. 7.70%c. 8.80%d. 9.90%

In 2007, americans smoked 19.2 billion packs of cigarettes. they paid an average retail price of $4.50 per pack. a. given that the elasticity of supply is 0.50.5 and the elasticity of demand is negative 0.4−0.4, derive linear demand and supply curves for cigarettes. the demand equation is qdequals=nothingplus+nothing times ×p and the supply equation is qsequals=nothingplus+nothing times ×p.

Gino's restaurant is a popular restaurant in boston, massachusetts. the owner of the restaurant has been trying to better understand costs at the restaurant and has hired a student intern to conduct an activity-based costing study. the intern, in consultation with the owner, identified the following major activities: activity cost pool activity measure serving a party of diners number of parties served serving a diner number of diners served serving drinks number of drinks ordered some costs, such as the cost of cleaning the linens that cover the restaurant's tables, vary with the number of parties served. other costs, such as washing plates and glasses, depends on the number of diners served or the number of drinks served. data concerning these activities are shown below. serving a party serving a dinner serving drinks total total cost $47,600 $153,000 $59,800 $260,400 total activity 7,000 parties 30,000 diners 46,000 drinks prior to the activity-based costing study, the owner knew very little about the costs of the restaurant. she knew that the total cost for the month was $260,400 and that 30,000 diners had been served. therefore, the average cost per diner was $8.68.required: 1. compute the activity rates for each of the three activities 2. according to the activity-based costing system, what is the total cost of serving each of the following parties of diners? a. a party of four diners who ordered three drinks in total b. a party of two diners who do not order any drinks c. a lone diner who orders two drinks 3. convert the total costs you computed in part (1) above to costs per diner. in other words, what is the average cost per diner for serving each of the following parties: a. a party of four diners who order three drinks in total b. a party of two diner who do not order any drinks c. a lone diner who orders two drinks 4. why do the costs per diner for the three different parties differ from each other and from the overall average coast of $9.80 per diner?

U.s. internet advertising revenue grew at the rate of r(t) = 0.82t + 1.14 (0 ≤ t ≤ 4) billion dollars/year between 2002 (t = 0) and 2006 (t = 4). the advertising revenue in 2002 was $5.9 billion.† (a) find an expression f(t) giving the advertising revenue in year t.
