I am having a tough time understanding a question for class. Basically, what I am trying to figure out is how she got the totals for Marginal cost.
If marginal cost equals the change in total cost divided by the change in quantity, then it should always be the change in quantity over 1 right? Which means just the actually change in quantity?
So on that graph it shows, ATC and Quantity, so TC=ATCxQ.
So does this make any sense?
For 2: ATC(7) X Q(2)= TC(14)
For 3: ATC(5.6)xQ(3)= TC(16.8)
So 14+x=18.8 x=2.8 She has 3.25
For 4: ATC(3.25) X Q(4)= TC(19.2)
So 16.8+X=19.2 X=2.4 She has 2.5
I just can\\\\\\\'t really see what to do here. Any help would be appreciated.
