Q: A supermarket receives a delivery of 15 cases of tins of beans. Each case contains 24 tins. If 5% of the tins are damaged and thrown away, how many tins of beans are left?
A: The supermarket has 15 cases × 24 tins / case = 360 tins of beans delivered to them. There are 360 tins × 0.05 = 18 tins that are damaged and unsellable. So in the end, there are 360 tins - 18 tins = 342 tins of beans that are left. The answer is 342.
Question: A store marks a book 30% above the cost. But during a sale, a 10% discount was given. If the book costs $50, what is the percent profit?
Answer: The store made a $50 x 30 / 100 = $15 profit for selling it 30% above the cost. So, the book was sold for $50 + $15 = $65. During a sale, the book’s selling price decreased by $65 x 10 / 100 = $6.50. So, the book was sold for $65 - $6.50 = $58.50. There was $58.50 - $50 = $8.50 profit after the discount. Therefore, the percent profit is $8.50 / $50 x 100% = 17%. The answer is 17.
[Question]Isabella has $45 more than Sam but only $15 more than Giselle. If Giselle has $120, calculate the total amount of money each shopper will receive if Isabella, Sam, and Giselle donate the money to three shoppers at their local town's supermarket who then decides to share it equally.
[Answer]If Isabella has $15 more than Giselle, she has $120 + $15 = $135. Combined, Isabella and Giselle has $135 + $120 = $255. Isabella has $45 more than Sam, meaning Sam has $135 - $45 = $90. Together, Sam, Isabella, and Giselle has $255 + $90 = $345. if they donate the money to three shoppers at their local town's supermarket who share it equally, each shopper will receive $345 / 3 = $115. The answer is 115.
Q: Beth is a scuba diver. She is excavating a sunken ship off the coast of a small Caribbean island and she must remain underwater for long periods. Her primary tank, which she wears when she first enters the water, has enough oxygen to allow her to stay underwater for 2 hours. She also has several 1-hour supplemental tanks that she takes with her as well as stores on the ocean floor so she can change tanks underwater without having to come up to the surface. She will need to be underwater for 8 hours. How many supplemental tanks will she need?
A: For an 8 - hour dive, she will use her 2 - hour primary tanks and will need supplemental tanks for 8 - 2 = 6 additional hours. Since each supplemental tank holds 1 hour of oxygen, for 6 hours she will need 6 / 1 = 6 supplemental tanks. The answer is 6.

The sum of black and white shirts is 63 + 42 = 105. The number of jeans in the store is (2 / 3) x 105 = 70. The sum of ties and belts is 34 + 40 = 74. The number of scarfs in the store is 74 / 2 = 37. There are 70 - 37 = 33 more jeans than scarfs in the store. The answer is 33.
