Question: Tom uses 10 weight plates each weighing 30 pounds on an exercise machine. This exercise machine uses special technology to make the weights 20% heavier on the lowering portion. How heavy did the weights feel when being lowered?
Answer: The weight stack weighed 10 * 30 = 300 pounds. So the added weight made it 300 * .2 = 60 pounds heavier. So when he lowered the weight it was 300 + 60 = 360 pounds. The answer is 360.
[Question]In 2021, Wayne is 37 years old. His brother Peter is 3 years older than him and their sister Julia is 2 years older than Peter. What year was Julia born in?

Question: The difference between the number of boys and girls in a tree planting event is 400. If there are 600 boys at the event, and the number of girls is more than the number of boys, what's 60% of the total number of boys and girls at the event?
Answer: If there are 600 boys at the event, and the difference between boys and girls is 400, there are 600 + 400 = 1000 girls. The total number of boys and girls at the event is 1000 + 600 = 1600. 60% of the total number of boys and girls at the event is 60 / 100 * 1600 = 960. The answer is 960.
[Question]Ben starts each day with $50, spends $15 every day and saves the rest. After a few days, his mom doubled his total savings and his dad gave him an additional $10. If he now has $500, How many days have elapsed?
[Answer]Let the number of days be x. He saves $50 - $15 = $35 each day. After x days he had saved $35 * x = $35x. His mom doubled his savings to give $35x * 2 = $70x. His dad added $10 to give $70x + $10 = $500. Subtracting 10 from both sides of the equation formed gives $70x = 490. Dividing both sides by $70 give x = 7 days. The answer is 7.
[Question]In the baking contest, three times as many people voted for the unicorn cake compared to the witch cake, and the number of votes for the dragon cake was 25 more than the number of votes for the witch cake. If 7 people voted for the witch cake, how many votes were cast total?
[Answer]
First find the number of votes for the unicorn cake: 7 votes * 3 = 21 votes. Then find the number of votes for the dragon cake: 25 votes + 7 votes = 32 votes. Then add the number of votes for each cake to find the total number of votes: 21 votes + 32 votes + 7 votes = 60 votes. The answer is 60.
