Q: James gets a fleet of gas transportation vans. He gets 6 vans. 2 of them are 8000 gallons. 1 of them is 30% less than that. The remaining trucks are 50% larger than the 2 trucks. How many gallons can he transport?
A: His smaller truck is 8000 * .3 = 2400 gallons smaller. So it can transport 8000 - 2400 = 5600 gallons. There are 6 - 2 - 1 = 3 of the very large trucks. Those trucks are each 8000 * .5 = 4000 gallons larger. So they can transport 8000 + 4000 = 12000 gallons. So in total they transport 3 * 12000 = 36000. The 8000 - gallon trucks can transport 8000 * 2 = 16000 gallons. So in total he can transport 5600 + 16000 + 36000 = 57600 gallons. The answer is 57600.
Question: While at the lake, Cohen saw 300 fish-eater birds that had migrated into the area recently walking by the lake, eating the fish they had caught. The number of birds at the lake doubled on the second day and reduced by 200 on the third day. How many fish-eater birds did Cohen see in the three days?
Answer: Since there were 300 fish - eater birds in the lake on the first day, the number doubled to 2 * 300 = 600 birds on the second day. The total number of fish that Cohen saw in the lake in the two days is 600 + 300 = 900. On the third day, the number of fish in the lake reduced to 600 - 200 = 400 birds. In the three days, Cohen saw 400 + 900 = 1300 fish - eater birds at the lake. The answer is 1300.
[Question]Five dozens of people are attending your family reunion. Your family was assigned to bring the cans of soda. Each box of soda contains 10 cans and costs $2 per box. It was assumed that each person can consume 2 cans of soda. If you are six in the family and agreed to pay equally for the cost, how much will each of your family members pay?
[Answer]Five dozens of people is equal to 5 x 12 = 60. 60 x 2 = 120 cans of soda are needed. So, this means 120 / 10 = 12 boxes of soda must be purchased. Thus, it will amount to $2 x 12 = $24. Therefore, each family member will pay $24 / 6 = $4. The answer is 4.
Q: Julieta went to the store to buy a backpack and three ring-binders for her school supplies. She knew the backpack was $50, and each ring-binder cost was $20. However, at the store, she found out that the price of a back had increased by $5, and the price of a ring-binder had reduced by $2. Calculate the total amount of money Julieta spent at the store.
A: Initially, a backpack cost was $50; when it increased by $5, the price became $50 + $5 = $55. The price of a ring - binder $20, when it reduced by $2, the price became $20 - $2 = $18. If she wanted to buy 3 ring - binders, she spent $18 * 3 = $54. In total, Julieta spent $55 + $54 = $109. The answer is 109.
Question: Mrs. Watson is grading 120 final exams from her American History class. On Monday, she grades 60% of the exams. On Tuesday, she grades 75% of the remaining exams. On Wednesday, how many more exams does she need to grade?
