Question: Tony has two fish. Every year, his parents buy him two more, but one of them dies. How many fish will he have in five years?
Answer: Each year Tony has one more fish than before because 2 - 1 = 1. In five years, he will have 5 more fish because 5 x 1 = 5. In five years he will have 7 fish because 2 + 5 = 7. The answer is 7.
[Question]Jerry’s two daughters play softball on different teams. They each have 8 games this season. Each team practices 4 hours for every game they play. If each game lasts for 2 hours, how many hours will Jerry spend at the field watching his daughters play and practice altogether?
[Answer]Jerry will spend 8 games x 2 hours per game = 16 hours watching one daughter play her games. He will spend 16 x 2 = 32 hours watching both daughters play their games. He will spend 8 games x 4 hours of practice = 32 hours watching one daughter practice. He will spend 32 x 2 = 64 hours watching both daughters practice. He will spend a total of 32 hours watching games + 64 hours watching practice = 96 hours. The answer is 96.
Q: Buying a toaster requires an insurance plan that is 20% of the MSRP, plus a mandatory state tax rate of 50% after the insurance plan calculation. Jon chooses to buy a toaster that costs $30 at MSRP. What is the total he must pay?
A: The insurance plan costs $30 * 0.2 = $6. The pre - state tax total is $30 + $6 = $36. State tax will be $36 * 0.5 = $18. Jon needs to pay $18 + $36 = $54 for his new toaster. The answer is 54.
Question: Mike is feeding the birds at the park. He counts out the seeds as he throws them. He throws 20 seeds to the birds on the left. He throws twice as much to the bigger group of birds on the right. Some more birds flutter over to join the others for lunch and Mike throws 30 more seeds for them. If Mike has 30 seeds left to feed the last of the birds, how many seeds did Mike start with?
Answer: Mike started by throwing 20 seeds to the birds and then threw twice as many, 20 + 20(2) = 20 + 40. That totals to 20 + 40 = 60 seeds. He also threw 30 other seeds and had 30 left over, which means he started with 60 + 30 + 30 = 120 seeds. The answer is 120.
[Question]Julian has 80 Facebook friends. 60% are boys and 40% are girls. Boyd has twice as many friends who are girls and has 100 friends total. What percentage of Boyd’s friends are boys?
