[Question]Thomas owns 200 books. He decides to sell them and use the money to buy records. Each book sells for $1.5. A record costs $3. If he buys 75 records, how much money does he have left over?
[Answer]He makes $300 selling the books because 200 x 1.5 = 300. He spends $225 on records because 75 x 3 = 225. He has $75 left because 300 - 225 = 75. The answer is 75.
Q: Alice was able to sell $2500 worth of gadgets. For this month, she expects to receive her monthly basic salary of $240 and a 2% commission from these sales. How much is she going to save this month if she usually saves 10% of her total earnings?
A: Alice will get $2500 x 2 / 100 = $50 from her commission. This month, she will receive a total of $240 + $50 = $290. Therefore, Alice will save $290 x 10 / 100 = $29 for this month. The answer is 29.
Question: This morning, farmer Rita's workers collected 30,000 gallons of milk and chilled it in a storage tank. They then spent the next 4 hours pumping milk at a rate of 2,880 gallons/hour from the storage tank into a milk tanker. For the next 7 hours, the workers added more milk into the storage tank, at a rate of 1,500 gallons per hour. How many gallons of milk were left in the storage tank?
Answer: In the first 4 hours, the milk tanker got 4 hours * 2880 gallons / hour = 11,520 gallons. Thus, the storage tank was left with 30,000 gallons - 11,520 gallons = 18,480 gallons. For the next 7 hrs, the workers added 1,500 gallons / hour * 7 hours = 10,500 gallons. The total therefore is 18,480 gallons + 10,500 gallons = 28,980 gallons. The answer is 28980.
[Question]Ahmed is 11 years old and Fouad is 26 years old. In how many years will Fouad's age be double Ahmed's current age?
[Answer]Let X be the number of years before Fouad's age doubles Ahmed's age. So (X + 11) * 2 = X + 26. So X * 2 + 22 = X + 26. So X = 26 - 22 = 4 years. The answer is 4.
[Question]Brian has twice as many tennis balls as Frodo, who has 8 more than Lily. If Lily has 3 tennis balls, how many does Brian have?
