Kimpel Products makes pizza ovens for commercial use. James Kimpel, CEO, is contemplating producing smaller ovens for use in high school and college kitchens. The activities necessary to build an experimental model and related data are listed in the following table:

Activity	Normal Time (weeks)	Crash Time (weeks)	Normal Cost	Total Cost with crashing	Immediate Predecessor(s)
A	3	2	$1200	$1800
B	2	1	$2300	$3000
C	1	1	$350	$350
D	7	3	$1300	$1580	A
E	6	3	$950	$1100	B
F	2	1	$4250	$5450	C
G	4	2	$1800	$2500	D, E

a) Based on the given information regarding the activities for the project, the project completion date = ? weeks.

b) For reducing the duration of the project to 10 weeks at the least cost, following is the order of that needs to be followed while crashing the activities:

The first activity to crash is ? by 2 weeks at a per week crashing cost of ? dollars.

Next, one should crash activity D and activity ? by 2 weeks each at a total per week crashing cost of ? dollows.

c) New requirements are to reduce the project to 7 weeks. Continuing to crash the activities from 10 weeks based on the above crashing already completed, following is the order for crashing:

Next activity to crash in order is ? by 2 weeks at a per week crashing cost of ? dollars.

Next, one should crash activity ? and activity E by 1 week at a total per week crashing cost of ? dollars.

Total cost of crashing the project to 7 weeks = ? dollars.
