She should consider how much the car will cost in comparison with the other uses for her funds combined with the cost of another means of transportation.

Method 4 Cost - 10x10 + 12x100 = $1,300

After determining that method 2 is the cheapest method, I would suggest that the trucker use method 2. 3. I feel that Enron’s biggest problem was the misappropriation of its profit and revenue. They did not do all they could to ensure that their fixed costs were covered while simultaneously managing their money. Instead they were victim of accounting fraud, frivolous spending, and corrupt management. Even simply replacing their upper management could have done wonders in preventing their fate.

I do not think these fixed costs can be ignored at all. However, if they must
