[Question]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?
[Answer]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 is 4400.
Q: John assembles computers and sells prebuilt computers as a business. The parts for the computer cost $800. He sells the computers for 1.4 times the value of the components. He manages to build 60 computers a month. He has to pay $5000 a month in rent and another $3000 in non-rent extra expenses a month. How much profit does he make a month?
A: He sells each computer for 1.4 * 800 = $1120. That means he makes a profit of 1120 - 800 = $320 per computer. So he makes 320 * 60 = $19200 from selling computers. He has extra expenses of 5000 + 3000 = $8000 a month. So his profit is 19200 - 8000 = $11,200. The answer is 11200.

Q: Kevin has a shoebox filled with toads. Every day, Kevin feeds each toad 3 worms. It takes Kevin 15 minutes to find each worm. If it takes Kevin 6 hours to find enough worms to feed all of his toads, how many toads does Kevin have in his shoebox?
A: If it takes 15 minutes to find each worm, then he catches 60 / 15 = 4 worms per hour. In 6 hours, Kevin catches 4 * 6 = 24 worms. If he feeds each toad 3 worms, then he has 24 / 3 = 8 toads in his shoebox. The answer is 8.
