answer
total cost
question

answer
false
question
A firm sells 10 shoes for $400, and incurs a total cost of $100. The firm makes an average profit of _____.
answer
$30
-Total profit = total revenue - total cost = $400 - $100 = $300.
-Average profit = total profit/quantity produced = $300/10 shoes = $30/shoe.
-Total profit = total revenue - total cost = $400 - $100 = $300.
-Average profit = total profit/quantity produced = $300/10 shoes = $30/shoe.

question
Josie, who was previously employed as a policewoman, owns a firm that produces burglary kits. She used to earn $1000 per month when she was a policewoman and she could return to that job if she wanted to do so. Now, she sells 500 kits in a month for $10 each. The cost of production is $2000.

$2,000
-Economic profit = 500 × 10 - 1,000 - 2,000 = $2,000
-Economic profit = 500 × 10 - 1,000 - 2,000 = $2,000
