[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]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. The answer is 3.
Q: Sixteen boys and 14 girls attended Simon's birthday party. Three-fourths of the boys and 6/7 of the girls brought gifts. How many of those who attended did not bring gifts?
A: 16 x 3 / 4 = 12 boys brought gifts. So, 16 - 12 = 4 boys did not bring gifts. 14 x 6 / 7 = 12 girls brought gifts. So, 14 - 12 = 2 girls did not bring gifts. Therefore, a total of 4 boys + 2 girls = 6 people did not bring gifts. The answer is 6.
Question: Dan is digging graves for a family killed by COVID-19. If it takes Dan 3 hours to dig an adult grave and 2 hours to dig a child's grave, how long does it take him to dig 5 adult graves and one child's grave?
Answer: First find the total amount of time Dan spends digging adult graves: 3 hours / grave * 5 graves = 15 hours. Then add the time to dig the child's grave to find the total time he spends digging: 15 hours + 2 hours = 17 hours. The answer is 17.
