Question: Dream's car consumes 4 gallons of gas per mile. If she drives 400 miles today and 200 more miles tomorrow than today, how many gallons of gas will the car consume?
Answer: If she drives 400 miles today, the car will have consumed 4 * 400 = 1600 gallons of gas. Tomorrow, if she drives 200 more miles, the total distance will be 200 + 400 = 600 miles. The fuel consumption by the car tomorrow is 4 * 600 = 2400 gallons. The car's total fuel consumption in the two days is 2400 + 1600 = 4000 gallons. The answer is 4000.
[Question]Lily goes to the supermarket. She has $60. She needs to buy 6 items: celery, cereal, bread, milk, potatoes, and coffee. She finds a stalk of celery for $5, cereal for 50% off $12, bread for $8, and milk for 10% off $10. She finds potatoes for $1 each and buys 6. How many dollars does she have left to spend on coffee?
[Answer]Lily spends $5 + $8 = $13 on celery and bread. Lily spends $12 * (50 / 100) = $6 on cereal. Lily gets 10% off the milk, so she pays 100% - 10% = 90% of its original price. Lily spends $10 * 90% = $9 on milk. She spends $1 * 6 = $6 on potatoes. Thus, she has $60 - $13 - $6 - $9 - $6 = $26 left over for coffee. The answer is 26.
Q: If Buzz bought a pizza with 78 slices at a restaurant and then decided to share it with the waiter in the ratio of 5:8, with Buzz's ratio being 5, what's twenty less the number of slices of pizza that the waiter ate?
A: The total ratio representing the slices of pizza that Buzz bought is 5 + 8 = 13. If he shared the slices of pizza with the waiter, the waiter received a fraction of 8 / 13 of the total number of slices, which totals 8 / 13 * 78 = 48 slices. Twenty less the number of slices of pizza that the waiter ate is 48 - 20 = 28. The answer is 28.
Question: Carmela has $7 and each of her four cousins has $2. How much will Carmela have to give to each of her cousins so that she and her cousins will have the same amount of money?
Answer: Carmela's four cousins have a total of $2 x 4 = $8. The total money they all have is $7 + $8 = $15. There will be 1 (Carmela) + 4 (cousins) = 5 people who will be sharing equally the money. So each of them should get $15 / 5 = $3. Hence, Carmela has to give a total of $7 - $3 = $4 to her 4 cousins. Therefore, each of her cousins will get $4 / 4 = $1. The answer is 1.
[Question]Danny has three picnics blankets. When they are unfolded they each have an area of 8 x 8. After he folds them up, their total area is 48 square feet. How many times did he fold them?
[Answer]The total area of each blanket is 8 * 8 = 64. Their total area is 192 square feet because 3 x 64 = 192. He folded them 4 times because 192 / 48 = 4. The answer is 4.
[Question]There are 40 Judges in the state of Rhode Island. 10 percent of Judges are under 30 years old. 60 percent of Judges are 30-50 years old. The rest of the Judges are over 50 years old. How many Judges are over 50 years old?
[Answer]
Under 30: 40(.10) = 4. 30 - 50 years old:40(.60) = 24. Over 50:40 - 4 - 24 = 12 Judges. The answer is 12.
