Determine the effect of each of the following situations on monthly profits. Each situation is to be evaluated independently of all others.

1. A $12 increase in the daily fee should result in a 150-unit decrease in monthly sales.
2. A $7 decrease in the daily fee should result in a 300-unit increase in monthly sales. However, because of capacity constraints, the last 100 guide-days would be provided by subcontracting to another firm at a cost of $46 per guide-day.
3. A tour agency has proposed to place a special, one-time order for 75 guide-days at a reduced fee of $45 per guide-day. The agency would pay all insurance costs. There would be additional fixed administration costs of $200.
