[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]Miss Aisha's legs are 1/3 of her total height. If her head is also 1/4 of her total height, and she is 60 inches tall, calculate the length of the rest of her body.
[Answer]Miss Aisha's legs are 1 / 3 * 60 = 20 inches. The length of her head is 1 / 4 * 60 = 15 inches. Together, her head and legs are 15 + 20 = 35 inches. If her total height is 60, the rest of her body has a length of 60 - 35 = 25 inches. The answer is 25.

[Question]Nancy takes 3 antacids per day when she eats Indian food, 2 antacids per day when she eats Mexican food, and 1 antacid per day otherwise. If Nancy eats Indian three times a week and Mexican twice a week, how many antacids does she take per month?
[Answer]First find the total number of antacids Nancy takes after eating Indian food per week: 3 antacids / day * 3 days / week = 9 antacids / week. Then find the total number of antacids Nancy takes after eating Mexican food per week: 2 antacids / day * 2 days / week = 4 antacids / week. Then find the number of days she doesn't eat Indian food or Mexican food: 7 days / week - 3 days / week - 2 days / week = 2 days / week. Then find the total number of antacids Nancy takes per week: 9 antacids / week + 4 antacids / week + 2 antacids / week = 15 antacids / week. Then multiply her weekly antacid consumption by the number of weeks per month to find her monthly consumption: 15 antacids / week * 4 week / month = 60 antacids / month. The answer is 60.
