Q: There are 4 wolves out hunting for the pack. The pack contains 16 additional wolves. Each wolf needs to eat 8 pounds of meat a day and the wolves won't hunt again for five days. If each deer contains 200 pounds of meat, how many deer does each wolf need to kill?
A: The wolf pack has 20 members because 4 + 16 = 20. They need 160 pounds of meat a day because 20 x 8 = 160. They need 800 pounds to last five days because 5 x 160 = 800. The hunters need to kill 4 deer because 800 / 200 = 4. They each need to kill one deer because 4 / 4 = 1. The answer is 1.

Q: One US cup equals 250ml. Brian is making lasagna for himself, his wife, his two kids, his parents, and his wife's parents. The recipe requires 1/2 a cup of milk per serving. How many 1L cartons of milk does Brian need to buy if each person is expected to eat 2 servings?
A:
There will be a total of (1) Brian + (1) Brian's wife + (2) two kids + (2) Brian's parents + (2) Brian's in - laws = 1 + 1 + 2 + 2 + 2 = 8 people eating. If 1 person eats 2 serving of lasagna then 8 people will eat 8 * 2 = 16 servings. If each serving requires 1 / 2 cup of milk then 16 servings require 16 * 1 / 2 cups = 8 cups of milk. If one cup of milk equals 250 ml, then 8 cups of milk equal 8 * 250 = 2000 ml of milk. 1L carton of milk equals 1000ml of milk, therefore Brian needs 2000 / 1000 = 2 cartons of 1L milk. The answer is 2.
