Sponsoring restaurants are paid $60 for each card sold, and card printing and distribution costs are $3 per card. This means that RMS's marginal costs are $63 per card.

    不曉得 $ 是什麼意思,我自動忽略

    1.

    Max. TR → MR = 0 ( 就是邊際收益不會再增加 )

    MR = 130- 0.00025Q = 0 → Q = 520000

    Q 代入需求,得 P = 130 - 0.000125.520000 = 65

    TR = P.Q = 520000.65 = 33800000

    π= TR - TC = 33800000 - 600000 - 63.520000 = 440000

    2.

    利潤最大條件 → MR = MC,所以

    130- 0.00025Q = 63 → Q = 268000

    Q 代入需求,得 P = 130 - 0.000125.268000 = 96.5

    TR = P.Q = 268000.96.5 = 25862000

    π= TR - TC = 25862000 - 600000 - 63.268000 = 8378000
