The Kwik-e-Tax Center charges $50 for a federal return, $30 for a state return, and $80 for quarterly business taxes. If they sell 60 federal returns, 20 state returns, and 10 quarterly returns in one day, what was their total revenue for the day? Let's answer step by step:
First find the total income from the federal returns: $50 / return * 60 returns = $3000. Then find the total income from the state returns: $30 / return * 20 returns = $600. Then find the total income from the quarterly returns: $80 / return * 10 returns = $800. Then add the income from each source to find their total income: $3000 + $600 + $800 = $4400. The answer: 4400.
