C没错的.设material的cost为m.总成本=3m且人力cost=2m;500,000-3m=利润;500,000-3m>2m那么,得m<100,000那么总成本3m<300,000最后得利润大于200,000

assfgrtrtr

total money = K = 500,000 K = L(labor) + materials(M) 問是否profit會大於150,000

條件1) >> K = 3M >> 不充分 條件2) >> profit > L >> 不充分

條件1)+條件2) K = 3M >> M = 500,000 / 3 and L = 2/3*(500,000) profit > L = 2/3*(500,000) > 150,000

故答案為(C)
