Answer:
See explanation.
Step-by-step explanation:
Average fixed costs = Fixed costs / Number of units produced.
AFC for,
1000 posters = 250 / 1000 = $0.250/poster
2000 posters = 250 / 2000 = $0.125/poster
10,000 posters = 250 / 10,000 = $0.025/poster
Average Total cost = (Fixed costs + variable costs) / Number of posters
ATC for,
1000 posters = 250 + 1000 / 1000 = $1.250/poster
2000 posters = 250 + 1000 + 800 / 2000 = $1.025/poster
10,000 posters = [250 + 1000 + 800 + (750*7)] / 10000 = $0.805/poster
there is no output level viable as even if the fixed costs were nullified and spread over a large production volume, the marginal cost of producing each poster after the initial 2000 is 750/1000 = 0.75 cents.
This means that @ 70 cents price, there will be a 0.05 cent marginal loss.
Hope that helps.
