AFC = total fixed cost/total output.
AVC = total variable cost/total output.
ATC = total cost/total output.
MC = change in total cost/change in output.
Total revenue = price * quantity. And given that the demand and supply intersect at $190, which implies that the equilibrium price is $190 because the point where the demand equals the supply determines the price.
MR = change in total revenue/change in output.
Profit = total revenue - total cost.
Average profit = total profit/total output.
Profit margin = total profit/total revenue*100 or (revenue - cost)/revenue*100.
Question:
a. What level of output should the manager of Redstone choose to produce? Explain your choice in 50-100 words.
b. Make a copy of your spreadsheet and triple the fixed costs to 21,000. How does this change your answer to question a? Explain your result in 50-100 words.
