[Question]A dog runs through a field and is joined by a group of 4 cats. 2 rabbits join each cat and 3 hares join each rabbit. How many animals are running through the field?
[Answer]A pair of rabbits join each cat so there must be 4 cats * 2 rabbits / cat = 8 rabbits. As 3 hares join each rabbit, there must be 8 rabbits * 3 hares / rabbit = 24 hares. Counting all the animals shows there are 1 dog + 4 cats + 8 rabbits + 24 hares = 37 animals running through the field. The answer is 37.

Question: Jean needs to buy 10 new pairs of pants. A store is running a sale for 20% off. If the pants normally retail for $45 each how much will she need to pay for all of them after paying a 10% tax?
Answer: The discount is 45 * .2 = $9 off each pair. So she pays 45 - 9 = $36 each. So it will cost 36 * 10 = $360 before tax. The tax will add 360 * .1 = $36. So she has to pay 360 + 36 = $396. The answer is 396.
Q: 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?
A:
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.
