A tech startup in Cyberport has total fixed cost of $1,000,000 and marginal cost of $50 per user. At what output level does average total cost equal $150?
A. 5,000 users
B. 10,000 users✓ 答案
C. 15,000 users
D. 20,000 users
解說
ATC = TFC/Q + MC. Set 1,000,000/Q + 50 = 150 → 1,000,000/Q = 100 → Q = 10,000.
