Explanation / Answer
From the demand schedule we first find the total revenue which is Price x Quantity and then find marginal revenue which is (TRn - TRn-1)/(Qn - Qn-1). This gives us the following table
Now MC = $4 and MR is greater and closest to MC at Q = 100. Thus, firm should produce 100 units. The price is $6 per unit
At this combination profit = TR - TC = (100*6) - (100 + 4*100) = $100 per day
Price elasticity using mid point is given by
Ed = (Q2 – Q1) / [(Q2 + Q1)/2] / (P2 – P1) / [(P2 + P1)/2]
= (160 - 100)/((160 + 100)/2) divided by (5 - 6)/((5 + 6)/2)
= -2.54
Now use P - MC / P = 6 - 4/6 = 0.33 and 1/2.54 = 0.39. Hence (P - MC)/P is less than 1/|ed|
Quantity Price TR MR MC 3 12 36 12.00 4 7 11 77 10.25 4 12 10 120 8.60 4 20 9 180 7.50 4 35 8 280 6.67 4 60 7 420 5.60 4 100 6 600 4.50 4 160 5 800 3.33 4 250 4 1000 2.22 4
