a) using the normal times, what is the critical path and project completion time for the budgeting process? also, what is the cost to complete the project based on the normal times?

b) if we want to reduce the project completion time to the minimum possible time by crashing activities, what is the new project completion time and what is the new total project cost?

c) modify the problem as follows. there is now an indirect cost of $75 per day, which is in addition to the cost identified above. there is also a penalty cost of $200 per day for any project completion time over 11 days. what is the minimum cost schedule for the project and what is the total cost for this schedule? identify what are the time and the path of this minimum cost schedule.

d) suppose that the company wants to crash the project 4 days. based on the information provided in the table and in part c) and the results from part c), what would the minimum penalty cost have to be for this to be supported by the economics in the problem? assume that the indirect cost remains at $75 per day.

Suppose either computers or televisions can be assembled with the following labor inputs: units produced 1 2 3 4 5 6 7 8 9 10 total labor used 3 7 12 18 25 33 42 54 70 90 (a) draw the production possibilities curve for an economy with 54 units of labor. label it p54. (b) what is the opportunity cost of the eighth computer? (c) suppose immigration brings in 36 more workers. redraw the production possibilities curve to reflect this added labor. label the new curve p90.

He cheyenne hotel in big sky, montana, has accumulated records of the total electrical costs of the hotel and the number of occupancy-days over the last year. an occupancy-day represents a room rented out for one day. the hotel's business is highly seasonal, with peaks occurring during the ski season and in the summer. month occupancy- days electrical costs january 1,736 $ 4,127 february 1,904 $ 4,207 march 2,356 $ 5,083 april 960 $ 2,857 may 360 $ 1,871 june 744 $ 2,696 july 2,108 $ 4,670 august 2,406 $ 5,148 september 840 $ 2,691 october 124 $ 1,588 november 720 $ 2,454 december 1,364 $ 3,529 required: 1. using the high-low method, estimate the fixed cost of electricity per month and the variable cost of electricity per occupancy-day. (do not round your intermediate calculations. round your variable cost answer to 2 decimal places and fixed cost element answer to nearest whole dollar amount) 2. what other factors other than occupancy-days are likely to affect the variation in electrical costs from month to month? (you may select more than one answer. single click the box with the question mark to produce a check mark for a correct answer and double click the box with the question mark to empty the box for a wrong answer.) seasonal factors like winter or summer. systematic factors like guests, switching off fans and lights. number of days present in a month. fixed salary paid to hotel receptionist. income taxes paid on hotel income.
