| Activity | Normal Time (Weeks) (a) |
Normal Cost (b) |
Crash Time (Weeks) (c) |
Crash Cost (d) |
Crash Limit (a-c) |
Total Crash Cost (d-b) |
Crash Cost Per Week |
| A | 8 | $1,750 | 7 | $2,200 | 1 | $450 | $450 |
| B | 8 | $4,200 | 4 | $6,600 | 4 | $2,400 | $600 |
| C | 10 | $4,700 | 8 | $5,700 | 2 | $1,000 | $500 |
| D | 6 | $2,000 | 4 | $4,000 | 2 | $2,000 | $1,000 |
First - Activity A since crash cost per week is the lowest ($450)
Second - Activity C since crash cost per week is the second lowest ($500)
Third - Activity C since crash cost per week is the second lowest ($500) and there is still limit left
