[請益] 個經的一個題目已刪文
For each carload of ore removed from the Matchless Mine, 1 pound of lead and 1
ounce of silver is smelted. The cost of mining and processing 1 carload of or
e is C(Q) = 700 + 2Q + 0.09Q2. The demand for silver (per ounce) is Ps = 40 -
0.30Qs and the demand for lead (per pound) is Pl = 5 - 0.02Ql. What should the
owners of the Matchless Mine do to maximize profits (in the long run)?
算了很久都算不出來...
有大大能幫忙解惑嗎感恩
