51.  As for the situation of B, there is a very possible implication that a growing amount of people will choose the alternative to buy private-owned moped as the available Mrs. Decrease by nearly 40 percent.

52.  In this situation, the whole amount of moped on B or rather the demand for moped on B is not reduced.

53.  In this situation, pedestrians will double and cram the streets of B.

54.  Supposing both Lily and Tom start from scratch and Lily is working for company A, while her counterpart Tom is working for company B.

55.  Without appropriate comparison between A and B, the assumption is unwarranted.

56.  Assumption B: assumption A is available in that specific industrial.

57.  Challenge yourself to get an A, when you only think your best is a B.

58.  Let's assume the odds are a, b and c.

59.  There is another formula to restrict the value of a, b and c: 1/a+1/b+1/c=t.

60.  Well, with these two formulas and some knowledge on inequality, we can calculate the maximum of (E/k) and the corresponding value of a, b and c (the value of E/k changes in response to the changes of a, b and c).
