Q: A big snowstorm caused a large amount of snow to fall onto Grandpa's farm, and the wind caused the snow to pile up into a drift. But on the second day, it warmed up enough that half of the snowdrift melted. The third day, it snowed again, adding another 6 inches of snow onto the snowdrift. On the fourth day, another 18 inches of snow fell onto the snowdrift. If the snowdrift was 34 inches deep at the end of the fourth day, how deep in inches was the drift at the end of the first day?
A: The third and fourth day contributed 6 + 18 = 24 inches to the depth of the snowdrift. Therefore, the size of the snowdrift after half was melted on the second day, but before the snowfall on the third and fourth day, was 34 - 24 = 10 inches. If the size of the drift on the second day, after half of the snow had melted, was 10 inches, then the depth of the original drift created on day 1 was 2 * 10 = 20 inches deep. The answer is 20.
Question: Pearl wants to order 5 monogrammed Christmas stockings for each of her 5 grandchildren and her own 4 children. The stockings are $20.00 each and currently 10% off. The monogramming will costs $5.00 per stocking. How much will the stockings costs?
Answer: She has 5 grandchildren 4 children so she needs 5 + 4 = 9 stockings. The stockings are $20.00 each and currently 10% off so that's 20 * .10 = $2.00 off. The stockings are $20.00 with a $2.00 discount so they are each 20 - 2 = $18.00. The stockings are now $18.00 and she needs 9 so that's $162.00. She also wants to monogram each stocking at $5.00 per stocking so that's 9 * 5 = $45.00. The stockings are $162.00 and the monogramming will cost $45.00 so the stockings will cost 162 + 45 = $207.00. The answer is 1035.
[Question]Matt's entire family was going to spend the week at the lake house for vacation. Matt's family included his mom, dad, his older brother and his wife and their 4 kids. His Uncle Joe and his wife were also coming and would bring their 3 kids. The house only sleeps 4 people. Everyone else would sleep 2 to a tent outside. How many tents would they need?
[Answer]We need to add Matt's entire family together so 1 + 2 + 2 + 4 + 2 + 3 = 14. Only 4 people could sleep in the house so 14 - 4 = 10 people would sleep in a tent. Each tent sleeps 2 people and there were 10 people left so 10 / 2 = 5 tents were needed. The answer is 5.
Q: Carla needs to bring water to her animals. Each horse needs twice as much water as a pig, and the chickens drink from one tank that needs 30 gallons. How many gallons of water does Carla need to bring if she has 8 pigs and 10 horses and each pig needs 3 gallons of water?
A: First figure out how much water all the pigs need: 8 pigs * 3 gallons / pig = 24 gallons. Then figure out how much water one horse needs by multiplying a pig's needs by 2: 3 gallons * 2 = 6 gallons. Now find how much water all the horses need: 10 horses * 6 gallons / horse = 60 gallons. Finally, add up all the animals' water needs: 24 gallons + 60 gallons + 30 gallons = 114 gallons. The answer is 114.
Question: The lifespan of a hamster is 6 years less than that of a bat. The lifespan of a frog is 4 times that of a hamster. Altogether, the lifespan of the animals is 30 years. What is the lifespan of the bat?
Answer: Let's set up an equation by calling the lifespan of a bat x, and therefore the lifespan of the hamster x 6, and the lifespan of the frog 4 (x 6) which add together to equal 30, like this: x + x 6 + 4 (x 6) = 30. That gives us 6x 30 = 30 and we should add 30 to each side to try to isolate the x. Now we have 6x = 60, which we will divide by 6, 6x / 6 = 60 / 6. This gives us x = 10. The bat has a lifespan of 10 years. The answer is 10.
Q: James can buy a new computer for $600 and have it last 6 years, or buy 2 used computers for $200 each that each last 3 years. How much money will he save by picking the cheaper option?
A:
First find the cost of the two used computers: $200 / computer * 2 computers = $400. Then subtract that cost from the cost of the new computer to find the savings: $600 - $400 = $200. The answer is 200.
