Quantity: 1,000 items
Price: $80 per item
Fixed cost: $20,000
Variable cost: $40 per item
The fixed cost stays the same, the total variable cost is:
Total variable cost (TVC) = variable cost * quantity
TVC = $40 * 1,000 = $40,000
Total costs = TVC + Fixed costs = $40,000 + $20,000 = $60,000
Te income is:
Income = price * quantity = $80 * 1,000 = $80,000
The profit is income minus total costs:
Profit = income - total costs = $80,000 - $60,000 = $20,000
Profit = $20,000
