Solution: Use the below formula to calculate crash cost/week
Crash Cost per period = (Crash Cost – Normal Cost) / (Normal time- Crash Time)
| Activity | Predecessors | Normal Time | Normal cost | Crash Time | Crash Cost | Crash Cost per period |
| A | 12 | $1,000.00 | 10 | $1,500.00 | $250.00 | |
| B | A | 5 | $1,200.00 | 3 | $1,950.00 | $375.00 |
| C | A | 9 | $1,500.00 | 7 | $2,100.00 | $300.00 |
| D | B,C | 14 | $1,800.00 | 10 | $2,100.00 | $75.00 |
| E | B,C | 4 | $1,400.00 | 3 | $1,875.00 | $475.00 |
| F | D | 9 | $1,000.00 | 8 | $1,450.00 | $450.00 |
| G | E | 7 | $700.00 | 5 | $1,200.00 | $250.00 |
| H | F,G | 11 | $2,000.00 | 8 | $3,000.00 | $333.33 |
| I | H | 8 | $1,100.00 | 6 | $1,700.00 | $300.00 |
