Question: Nicole has 4 fish tanks. The first two tanks need 8 gallons of water each and the other two need 2 fewer gallons of water each than the first two tanks. If Nicole needs to change the water of the aquarium every week, how many gallons of water will she need in four weeks?
Answer: Step-by-step reasoning process: The first two tanks need 8 x 2 = 16 gallons of water. The other two tanks need 8 - 2 = 6 gallons of water each. So, the two other tanks need 6 x 2 = 12 gallons of water. Nicole needs 16 + 12 = 28 gallons of water every week for her four tanks. Therefore, she needs a total of 28 x 4 = 112 gallons of water in four weeks.
So the answer is 112.

Question: A box of ice cream bars costs $7.50 and contains three bars. 6 friends want to each eat 2 bars. How much money will that require per person?
Answer: Step-by-step reasoning process: If 6 friends each want 2 bars, that's 6 friends * 2 bars = 12 bars needed. Each box contains 3 bars, so 12 bars / 3 bars per box = 4 boxes needed. A box is $7, so 4 boxes * $7.50 = $30. There are 6 friends so $30 / 6 friends = $5 per person.
So the answer is 5.

Question: Donald drinks 3 more than twice the number of juice bottles Paul drinks in one day. If Paul drinks 3 bottles of juice per day, how many bottles does Donald drink per day?
Answer: Step-by-step reasoning process: Twice the number of bottles Paul drinks in one day is 3 * 2 = 6 bottles. So, the number of bottles that Donald drinks in one day is 6 + 3 = 9 bottles.
So the answer is 9.

Question: Paul earns $12.50 for each hour that he works. He then has to pay 20% for taxes and fees. After working 40 hours, Paul receives his paycheck. If he spends 15% of his paycheck on gummy bears, how much, in dollars, does he have left?
Answer:
Step-by-step reasoning process: His pay before taxes and fees is $12.50 x 40 hours = $500. He pays $500 * 0.20 = $100 for taxes and fees. Then he had $500 - $100 = $400 remaining money. He takes out $400 * 0.15 = $60 for his gummy bears. So he's left with $400 - $60 = $340.
So the answer is 340.
