Im having trouble with filling in a table for MC TC and AC given a cost funchtion
The cost functon is C(q)= 50+.5q
im given q 1 through 7
Ive aready calculated TC for q=1 TC=50.5 for q=2 TC=51 and so on
MC is where im having Trouble.
i know MC = dC(q)/dq or change in cost over change in q.
my teacher is telling me that the MC for q=2 IS 51/2=25.5 But wouldnt MC= .5/1 ( 5150.5)/(21) I cant get him to respond to my emails and im panicing
Thanks

I agree with you, under your equation, MC is constant and equal to .5
