Answer:
The company should print the 3,000 units of Tennessee as they will yield a gain for 3,000 dollars.
Because it faces economies of scale it should sale for as much as it can from a given pattern
Explanation:
Profit: revenue - variable cost - fixed cost
Profit = 15*Q - 8*Q - 18,000
Profit = 7Q- 18,000
3,000 Tennessee shirts x $7 contribution per shirt - 18,000 setup cost
profit: 21,000 - 18,000 = 3,000
Profit maximization: Marginal revenue = marginal cost
Total Revenue: 15 x Q
dTR' /dQ = 15
dTR''/dQ = 0
cost function: 18,000 + 7Q
dC'/dQ = 7
dC''/dQ = 0
Sport Tee faces a economie of scale their cost do not increase over time. Sport Tee should sale as many shirt as it possible can
