Activity	1	2	3	4	5	6	7	8
A	20
B		15	15
C		20	20
D				5	5	5
E							10
F							10	10
G					15
Total Resources/Day	20	35	35	5	20	5	20	10
Cumulative Figure	20	55	90	95	115	120	140	150

Total Resources/Day — Total Resources/Day 1 2 3 4 5 6 7 8

Cumulative Figure - Cumulative Figure 1 2 3 4 5 6 7 8

After resource loading:
