Auniversity spent $1.8 million to install solar panels atop a parking garage. these panels will have a capacity of 400 kilowatts (kw) and have a life expectancy of 20 years. suppose that the discount rate is 20%, that electricity can be purchased at $0.10 per kilowatt-hour (kwh), and that the marginal cost of electricity production using the solar panels is zero. hint: it may be easier to think of the present value of operating the solar panels for 1 hour per year first. approximately how many hours per year will the solar panels need to operate to enable this project to break even? a. a.3,696.48 b.14,785.92 c.9,241.20 if the solar panels can operate only for 8,317 hours a year at maximum, the project (would/would not)break even?

3. saving two consumers, larry and jeff, have utility functions defined over the two periods of their lives: middle age (period zero) and retirement (period 1). they have the same income in period 0 of m dollars and they will not earn income in period 1. the interest rate they face is r. larry’s and jeff’s utility functions are as follow. = 0.5 + 0.5 and = 0.5 + 0.5 for each person is between zero and one and represents each consumer’s temporal discount econ 340: intermediate microeconomics. ben van kammen: purdue university. rate. a. write the budget constraint that applies to both jeff and larry in terms of consumption in each period and ), interest rate, and m. b. what is larry’s and what is jeff’s marginal rate of intertemporal substitution? c. what is the slope of the budget constraint? d. write each consumer’s condition for lifetime utility maximization. e. re-arrange the conditions from part (d) to solve for the ratio, . f. if > which consumer will save more of his middle age income? g. if > 1 1+ , in which period will larry consume more: = 0 or = 1?

Pestiferous manufacturing produces a chemical pesticide and uses process costing. there are three processing departmentslong dash​mixing, ​refining, and packaging. on january​ 1, the first departmentlong dashmixinglong dashhad no beginning inventory. during​ january, 48,000 fl. oz. of chemicals were started in production. of​ these, 40,000 fl. oz. were​ completed, and​ 8,000 fl. oz. remained in process. in the mixing​ department, all direct materials are added at the beginning of the production​ process, and conversion costs are applied evenly throughout the process. at the end of​ january, the equivalent unit data for the mixing department were as​ follows: units equivalent units equivalent units units to be accounted for direct materials costs conversion costs completed and transferred out ​40,000 ​40,000 ​40,000 ending​ work-in-process* ​8,000 ​8,000 ​3,520 ​48,000 ​48,000 ​43,520 ​* percent complete for conversion​ costs: 44% in addition to the​ above, the cost per equivalent unit were​ $1.35 for direct materials and​ $5.30 for conversion costs. using this​ data, calculate the full cost of the ending wip balance in the mixing department. the​ weighted-average method is used.
