Consider the following three companies:

(i) Gasco owns and operates a chain of gas stations in the northeast United States.

(ii) Fuelco is a prerevenue company that is attempting to develop new fuel cell technologies to replace the internal combustion engine.

(iii) Combco combines the operations of Gasco and Fuelco.

Use qualitative reasoning to order the cost of capital for these three companies from lowest to highest. (There is more than one reasonable way to answer this question, but there are also wrong ways to answer.)
