Question: 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.
Answer: 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.

Answer: For the short stack orders, Hank needs to make 3 x 9 = 27 pancakes. For the big stack orders, he needs to make 5 x 6 = 30 pancakes. Altogether, Hank needs to make 27 + 30 = 57 pancakes. The answer is 57.

Question: Ishmael was monitoring whales out at sea for conservation purposes. Each time he takes a trip to sea, he sees a different group of whales. On his first trip, he counts 28 male whales and twice as many female whales. On his second trip, he sees 8 baby whales, each travelling with their parents. On his third trip, he counts half as many male whales as the first trip and the same number of female whales as on the first trip. In total, how many whales were out at sea during Ishmael’s monitoring?
Answer: On the first trip, Ishmael sees 28 male whales * 2 = 56 female whales. So in total, he sees 28 male whales + 56 female whales = 84 whales on the first trip. On the second trip, each baby whale travels with its parents which means it travels in a group of 1 baby whale + 2 parents = 3 whales / baby whale. This means there are 8 baby whales * 3 whales / baby whale = 24 whales on the second trip. On the third trip, there are half as many male whales as there were on the first trip, so there must be 28 male whales / 2 = 14 male whales. Adding this to the female whales means he saws 14 males whales + 56 female whales = 70 whales on the third trip. In total, Ishmael saw 84 + 24 + 70 = 178 whales across the three trips. The answer is 178.

Question: In seven years, Talia will be 20 years old. Talia's mom is currently three times as old as Talia is today. In three years, Talia's father will be the same age as Talia's mom is today. Currently, how many years old is Talia's father?
Answer:
In seven years, Talia will be 20 years old, and therefore Talia is currently 20 - 7 = 13 years old. Talia's mom is currently three times as old as Talia is today, or 3 * 13 = 39 years old. If in three years, Talia's father will be the same age as Talia's mom is today, then Talia's father is currently 39 - 3 = 36 years old. The answer is 36.
