请高人帮忙....
Consider the following information about bread production at Beth's Bakery:
Worker Marginal Product
1 5
2 7
3 10
4 11
5 8
6 6
7 4
Beth pays all her workers the same wage and labour is her only variable cost. From this information we can conclude that Beth's marginal cost
1) declines as output increases from 0 to 11, but increases after that.
2) declines as output increases from 0 to 33, but increases after that.
3) increases as output increases from 0 to 11, but declines after that.
4) continually increases as output rises.
下一道...
Assume a certain firm is producing 1,000 units of output (so Q = 1,000). At Q = 1,000, the firm's marginal cost equals $15 and its average total cost equals $11. The firm s
先把numbers of worker is x-axis, plot in total production:
X Y
1 5
2 12
3 22
4 33
5 41
6 47
7 51
就是把第 2 个数字加到前面的得到的数, from the fourth worker and on , you can observe that there's diminishing rate of return (ex: 11到8)所以要选。
你的意思是，答案应该是2，。。。我知道了~因为我刚才是用marginal rate 来看,问题是说output, diminishing return starts from the fourth worker, and thus with each additional output, the marginal cost increases, as you can see from the above table I have provided, the total output of the first four workers is 33, which explains that the marginal cost increases from 33 outputs...
第2题是4) 1003: (12-11)*1000-12+15
addition:
marginal output means for each additional worker there's certain numbers of additional output... so: with additional of one worker to the first worker: (2 workers working, the output would be 5+7=12, and add another worker (now 3 workers are working) 12+10=22.
