​c) Total cost of crashing the project by 2 days​ = ​$_________ ​(Enter your response as an​ integer.)

**Project Crashing Details for Computer Installation**

Three activities are candidates for crashing on a project network for a large computer installation project. The details of these activities, which are all critical, are summarized in the table below:

| Activity | Normal Time (days) | Crash Time (days) | Normal Cost | Total Cost with Crashing | Immediate Predecessor(s) |
|----------|--------------------|-------------------|-------------|--------------------------|--------------------------|
| A        | 7                  | 6                 | $5,000      | $5,500                   | —                        |
| B        | 4                  | 2                 | $1,400      | $3,100                   | A                        |
| C        | 11                 | 9                 | $4,200      | $6,200                   | B                        |

**Explanation:**

- **Activity A**: Normally takes 7 days and costs $5,000. If crashed, it takes 6 days at a cost of $5,500.
- **Activity B**: Normally takes 4 days and costs $1,400. If crashed, it takes 2 days at a cost of $3,100. It must be preceded by Activity A.
- **Activity C**: Normally takes 11 days and costs $4,200. If crashed, it takes 9 days at a cost of $6,200. It must be preceded by Activity B.

This table helps in determining the trade-offs between time and cost for project management decisions.
