During november, the production department of a process operations system completed and transferred to finished goods 35,000 units that were in process at the beginning of november and 110,000 units that were started and completed in november. november's beginning inventory units were 100% complete with respect to materials and 55% complete with respect to conversion. at the end of november, 40,000 additional units were in process in the production department and were 100% complete with respect to materials and 30% complete with respect to conversion. compute the number of equivalent units with respect to materials for november using the weighted-average method.
a. 145,000.
b. 40,000.
c. 105,000.

Dr. dow jones wants to know whether a problem-based approach to teaching economics will result in higher academic performance than his traditional method. of the six sections of economics 101 at his university, dr. jones randomly assigns three sections to the traditional method and three sections to the problem-based method for unit 1 of the course. then all sections switch the instructional method for unit 2. he plans to compare the performance of the two groups of sections on their unit 1 and unit 2 exams. this study employs a design.

Annuity payments are assumed to come at the end of each payment period (termed an ordinary annuity). however, an exception occurs when the annuity payments come at the beginning of each period (termed an annuity due). what is the future value of a 13-year annuity of $2,800 per period where payments come at the beginning of each period? the interest rate is 9 percent. use appendix c for an approximate answer, but calculate your final answer using the formula and financial calculator methods. to find the future value of an annuity due when using the appendix tables, add 1 to n and subtract 1 from the tabular value. for example, to find the future value of a $100 payment at the beginning of each period for five periods at 10 percent, go to appendix c for n = 6 and i = 10 percent. look up the value of 7.716 and subtract 1 from it for an answer of 6.716 or $671.60 ($100 × 6.716)
