Q: John receives $100 from his uncle and gives his sister Jenna 1/4 of that money. He goes and buys groceries worth $40. How much money does John have remaining?
A: When John gives his sister 1 / 4 of his money, he parts with 1 / 4 * 100 = 25 dollars. Johns remains with 100 - 25 = 75 dollars. When he buys groceries worth $40, he remains with 75 - 40 = 35 dollars. The answer is 35.
Question: Tom wants to visit Barbados. He needs to get 10 different vaccines to go and a doctor's visit. They each cost $45 and the doctor's visit costs $250 but insurance will cover 80% of these medical bills. The trip itself cost $1200. How much will he have to pay?
Answer: The medical cost comes out to 45 * 10 + 250 = $700. Insurance covers 700 * .8 = $560. So he has to pay 700 - 560 = $140. Added to the cost of the trip he has to pay 1200 + 140 = $1340. The answer is 1340.

Question: Asha has to buy some gifts but has no money. She decides to borrow $20 from her brother, $40 from her father, $30 from her mother and is gifted $70 by her granny. She adds this to her savings of $100 and goes out to Target to get what she wanted. If she spent 3/4 of the money, how much money did she remain with?
Answer: With the amount borrowed from her family, she has a total of 20 + 40 + 30 = 90 dollars. With the amount gifted from her granny, she has 70 + 90 = 160 dollars. She adds this to her savings, ending up with a total of 160 + 100 = 260 dollars. She spends 3 / 4 of this money, which is 3 / 4 * 260 = 195 dollars. The total she remains with is 260 - 195 = 65 dollars. The answer is 65.
Q: Kenny wants to make sure he does more jumping jacks every week than he did the week before. He recorded that last week he did 324 total jumping jacks. On Saturday of this week, he looks at his records and sees that on Sunday he did 34. On Monday he did 20. On Tuesday he skipped a day. On Wednesday he did 123. On Thursday he did 64. On Friday he did 23. How many does he have to do on Saturday to make sure he beats last week's number?
A:
He has already done 264 this week because 34 + 20 + 123 + 64 + 23 = 264. If he does 60 he will have done as many as last week because 324 - 264 = 60. He has to do 61 on Saturday because 60 + 1 = 61. The answer is 61.
