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 with step-by-step thinking: 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.
So the answer is 4400.

Question: Stacy went to a store to buy some pairs of shorts. Each pair normally cost $10, but there's a discount of 10% on the total cost for people who purchase 3 or more pairs at once. How much can she save by buying 3 pairs at once as opposed to purchasing them individually at different times?
Answer with step-by-step thinking: Without the discount, each pair cost $10 so 3 pairs cost 3 * $10 = $30. With a discount of 10% on the total cost, she can pay only $30 - ($30 * (10 / 100)) = $27. By buying 3 at once in order to get the discount, she can save $30 - $27 = $3.
So the answer is 3.

Question: Aaron pays his actuary membership fees each year. The membership fee increases yearly by $10. If he pays $80 in the first year, how much does his membership cost, in dollars, in the sixth year?
Answer with step-by-step thinking:
In year 2 he pays 80 + 10 = $90. In year 3 he pays 90 + 10 = $100. In year 4 he pays 100 + 10 = $110. In year 5 he pays 110 + 10 = $120. In year 6 he pays 120 + 10 = $130.
So the answer is 130.
