[Question]Chip has a $50.00 balance on his credit card. Since he didn't pay it off, he will be charged a 20% interest fee. He puts $20.00 on his credit card the following month and doesn't make any payments to his debt. He is hit with another 20% interest fee. What's the current balance on his credit card?
[Answer]He has a balance of $50.00 and is charged 20% interest so that's 50 * .20 = $10.00. He had a balance of $50.00 and now has a $10.00 interest fee making his balance 50 + 10 = $60.00. His balance is $60.00 and he puts another $20.00 on his card for a total of 60 + 20 = $80.00. He didn't make a payment that month and is hit with another 20% interest fee so that's 80 * .20 = $16.00 in interest. His new balance is 80 + 16 = $96.00. The answer is 96.
Q: If a bunny comes out of its burrow 3 times per minute, calculate the combined number of times 20 bunnies at the same pace will have come out of their burrows in 10 hours.
A: If a bunny comes out of its hole three times in a minute, in an hour, with 60 minutes, the bunny will come out of the hole 60 * 3 = 180 times. In 10 hours, a bunny will come out of their hole 180 * 10 = 1800 times. The combined time that 20 bunnies coming out of their holes will have taken in 10 hours is 1800 * 20 = 36000 times. The answer is 36000.
Question: James collects all the fruits from his 2 trees. Each tree has 20 plants. Each plant has 1 seed and he plants 60% of those. How many trees did he plant?

[Question]On his farm, Mr. Valentino has 200 chickens, twice as many ducks as chickens and three times as many turkeys as ducks. How many birds does Mr. Valentino have on the farm in total?
[Answer]Mr. Valentino has twice as many ducks as chicken on his farm, which means there are 2 * 200 = 400 ducks on the farm. The number of turkeys is three times as many as the number of ducks on Mr. Valentino's farm, a total of 3 * 400 = 1200 turkeys. In total, Mr. Valentino has 1200 + 400 = 1600 ducks and turkeys on his farm. If you add the number of chickens on the farm, the number of birds on the farm becomes 1600 + 200 = 1800 birds. The answer is 1800.

Question: Hadley loves to do volunteer work at the local library. On a certain day, she neatly arranges 100 books on the shelf. By lunchtime, a certain number of books had been borrowed. She added 40 more books to the same shelf. By evening, 30 more books had been borrowed. If the shelf had 60 books remaining by the evening, how many books had been borrowed by lunchtime?
Answer:
Let x be the number of books borrowed by lunchtime. So by lunchtime, the remaining number of books will be 100 - x. After adding 40 more books, the total number of books increased to 100 - x + 40. By evening, after 30 more books have been borrowed, the total number of books remaining is 100 - x + 40 - 30 = 60. Thus 110 - x = 60. Thus x = 50 books. The answer is 50.
