Answer:
$-150
Step-by-step explanation:
Sales Revenue = 18 handbags per month X $100 per handbag
= $1,800
Variable costs = 18 handbags X $50 cost per handbag
= $900
Juliana's Net Income = $1,800 - $900
= $900
Juliana's opportunity costs = $250 for renting guest room + $800 at job
= $1050
Juliana's Economic Profit = Net Income - Total Opportunity Costs
= $900 - $1,050
= -$150
Hence, her economic profit is actually a negative 150 dollars.
