First, determine the profit for a certain year by subtracting the total cost from the total revenue.
Total revenue = $1,000,000
Total Cost = $700,000 + $100,000 + $80,000 + $10,000
Total cost = $890,000
The revenue is calculated below,
Revenue = $1,000,000 - $890,000
R = $110,000
The tax is calculated by multiplying the revenue by the percentage given.
Tax = ($110,000)(0.30)
Tax = $33,000
Answer: $33,000
