Q: Mr. Jesiah is a dairy cow farmer with cows producing 200 gallons of milk every day. The expenses for maintenance of the dairy farm and purchase of feeds is $3000 per month. Calculate his total income in June if he sells 1 gallon of milk at $3.55.
A: In a day, Mr. Jesiah's total income from the sale of the milk is $3.55 / gallon * 200 gallons / day = $710 / day. In June, his total income is $710 / day * 30 days = $21300. The net income from the sale is $21300 - $3000 = $18300. The answer is 18300.
Question: Thomas made 4 stacks of wooden blocks. The first stack was 7 blocks tall. The second stack was 3 blocks taller than the first. The third stack was 6 blocks shorter than the second stack, and the fourth stack was 10 blocks taller than the third stack. If the fifth stack has twice as many blocks as the second stack, how many blocks did Thomas use in all?
Answer: The second stack has 7 blocks + 3 blocks = 10 blocks. The third stack has 10 blocks - 6 blocks = 4 blocks. The fourth stack has 4 blocks + 10 blocks = 14 blocks. The fifth stack has 10 blocks x 2 = 20 blocks. In total there are 7 blocks + 10 blocks + 4 blocks + 14 blocks + 20 blocks = 55 blocks. The answer is 55.
[Question]Xander read 20% of his 500-page book in one hour. The next night he read another 20% of the book. On the third night, he read 30% of his book. How many pages does he have left to read?
[Answer]The first night he read 20% of his 500 - page book so he read .20 * 500 = 100 pages. The book is 500 pages and he read 100 so that leaves 500 - 100 = 400 pages. The second night he reads 20% of the 500 pages so he read .20 * 500 = 100 pages. The book is now 400 pages and he read 100 so that leaves 400 - 100 = 300 pages. The third night he read 30% of the book so he read .30 * 500 = 150 pages. The book is now 300 pages and he read 150 pages so he has 300 - 150 = 150 pages left to read. The answer is 150.
Q: Simon and Peter have a big stamp collection. Simon collects red stamps and Peter collects white stamps. Simon has 30 red stamps and Peter has 80 white stamps. If the red stamps are then sold for 50 cents each and the white stamps are sold for 20 cents each, what is the difference in the amount of money they make in dollars?
A: Red stamps are 50 cents each and for 30 stamps, Simon would get 50 * 30 = 1500 cents. White stamps are 20 cents each and for 80 stamps, Peter would get 20 * 80 = 1600 cents. The difference in cents is 1600 - 1500 = 100 cents. One dollar equals 100 cents, so the difference in dollars is 100 / 100 = $1. The answer is 1.
Question: A store owner repacked his oils into 200 mL bottles. He was able to make 20 bottles. How many liters of oil did the store owner have?
Answer: Twenty bottles of oil is equal to 200 mL x 20 = 4000 mL. Since 1 liter is equal to 1000 mL, then the store owner had 4000 / 1000 = 4 liters of oil. The answer is 4.
