At a price of $3.00 per pack, the raspberry farm produces 70 packs where P = MR = MC, and average cost at that quantity is also $3.00. What is the farm's profit?
A$210, a large profit
B$70, a small profit
CNegative $70, a loss
D$0, the farm breaks even
Answer & Solution
Correct answer: D. $0, the farm breaks even
1. Profit equals (price minus average cost) times quantity.
2. Here price and average cost are both exactly $3.00, so price minus average cost is $0.
3. Multiplying $0 by any quantity still gives $0 in profit.
4. This is the zero-profit case, where price equals average total cost exactly, not a loss or a large profit.
