Development of Version 2.0 of a particular accounting software product is being considered by Jose? Noguera’s technology firm in Baton Rouge. The activities necessary for the completion of this project are listed in the following? table:

Activity	Normal Time? (weeks)	Crash Time? (weeks)	Normal Cost	Total Cost with Crashing	Immediate? Predecessor(s)
A	4	3	$2,200	$2,800	—
B	2	1	$2,200	$2,800	—
C	3	3	$500	$500	—
D	8	4	$2,500	$2,820	A
E	6	3	$900	$1,350	B
F	3	2	$3,200	$4,600	C
G	4	2	$1,500	$2,000	?D, E

?a) Based on the given information regarding the activities for the? project, the project length? = ____weeks.

b) The total cost required for completing this project on normal time = $___________

c) For reducing the duration of the project by one week, the activity that should be crashed first is activity _________. The cost of the project based on the first activity selected for crashing will increase by $_________.

d) The maximum weeks by which the project can be reduced by crashing = _________weeks

A forest originally has 10,000 trees. Suppose that the forest naturally replenishes itself by 10 percent per year. That is, at the end of one year, if nothing else happened, it would have 10,000 + (0.10 × 10,000) = 11,000 trees. (This assumption is not biologically accurate, but it keeps the math simple.) Suppose that 1,500 trees are harvested at the end of each year.

a. How many trees will the forest have at the end of one year, after accounting for both natural replenishment and the effects of harvesting?

b. Draw a stock flow diagram illustrating the ange in the forest stock from year 1 to year 2.

c. How many trees will there be at the end of two years? (Note: Base the 10 percent replenishment amount on the number of trees that exist at the beginning of the second year.)

d. How many trees will there be at the end of three years?

e. For the harvest of trees to be sustainable, what is the largest number of trees that could be harvested each year (starting with the original stock of 10,000 trees)?
