According to six-tenths-factor rule, if the cost of a given unit at one capacity is known, then the cost of similar unit with " times the capacity of the first unit is approximately equal to _____________ times the cost of the initial unit?
Correct answer: B. n0.6
- A. n
- B. n0.6
- C. n0.4
- D. √n
Explanation
The six-tenths rule expresses cost scaling as \(C_2/C_1=(Q_2/Q_1)^{0.6}\). Thus, increasing capacity by a factor of n increases the estimated cost by approximately \(n^{0.6}\), not by n itself.
