Q: Stephanie is checking her household budget, and needs to calculate how much she has left to pay for her bills. Her electricity bill costs $60, and this is paid in full. Her gas bill was $40, and she has already paid three-quarters of this. She makes another payment of $5 towards her gas bill while checking her budget. Her water bill is $40, which she has paid half of, and her internet bill is $25, which she has made 4 payments of $5 towards. Overall, how many dollars does Stephanie still need to pay to finish paying her bills?
A: Stephanie has paid three - quarters of her gas bill, which is 40 * 0.75 = $30. She then made another payment, which means she has paid 30 + 5 = $35 of her gas bill. She has paid half of her water bill, which is 40 * 0.5 = $20. She has made 4 payments towards her internet bill, which is a total of 4 * 5 = $20. Overall, her bills were 60 + 40 + 40 + 25 = $165. Overall, she has made payments of 60 + 35 + 20 + 20 = $135. Therefore, she still has to pay 165 135 = $30. The answer is 30.

Question: Bob bought 2 show dogs for $250.00 each to breed as a side business. The female just had a litter of 6 puppies. If he sells each puppy for $350.00, what is his total profit?
Answer: He bought 2 dogs for $250.00 each so they costs 2 * 250 = $500.00. He sells each of the 6 puppies for $350.00 so he'll make 6 * 350 = $2,100.00. He made $2,100 on the puppies but spent $500.00 to buy the dogs so his total profit is 2,100 - 500 = $1,600.00. The answer is 1600.
Q: The space station, Lupus-1, is an enormous spacecraft made up of three identical cylindrical structures that house the living quarters for the crew. The three cylindrical structures are linked together by a series of tunnels that hold them together and allow the crew to move between cylinders. Each cylindrical structure contains 12 bedrooms, 7 bathrooms, and several kitchens. If the entire space station has 72 rooms, how many kitchens are there on the entire space station?
A:
If there are 3 identical cylindrical structures, with a combined total of 72 rooms, then each individual cylindrical structure contains 72 / 3 = 24 rooms. In each 24 - room cylindrical structure, there are 24 - 12 - 7 = 5 kitchens. Thus, the entire, three - cylinder space station contains a total of 3 * 5 = 15 kitchens. The answer is 15.
