Given the data and information that follow, compute the total direct cost for each project duration. The indirect costs for each project duration are shown in the following table:

Time units	Indirect costs
15	90
14	70
13	50
12	40
11	30

Activity	Crash cost	Maximum
ID	(Slope)	Crash Time	Normal time	Normal cost
A	30	1	5	50
B	60	2	3	60
C	0	0	4	70
D	10	1	2	50
E	60	3	5	100
F	100	1	2	90
G	30	1	5	50
H	0	0	2	60
I	200	1	3	200
	Total direct normal costs			$730
