In order to complete the table first, the fixed cost is to be found.
Now according to the table, the MC of manufacturing 0 units is 2 hence the initial fixed cost is to be 2 units.
The fixed cost stays constant throughout.
The TC is found by adding FC+MC=AC
ATC=AC/Q.
TFC=FC*Q.
AVC=ATC/Q.
MC=TC(n)-TC(n-1).
USe the above formula to fill the table.
C) In order to maximize profit use the condition MC=MR which is given at a point where both are 6 units that are at quantity 7 units.
D)The total profit would be at 7units and would correspond to the profit of 16.03 units.
The point is graphically represented by the point where the line MC cuts the constant line MR.
