Question and rationale: The question is: Arnold's collagen powder has 18 grams of protein for every 2 scoops. His protein powder has 21 grams of protein per scoop. And his steak has 56 grams of protein.  If he has 1 scoop of collagen powder, 1 scoop of protein powder and his steak, how many grams of protein will he consume?
Step-by-step reasoning process: 2 scoops of collagen powder have 18 grams of protein and he only has 1 scoop so he consumes 18 / 2 = 9 grams of protein. He has 9 grams collagen powder, 21 grams of protein powder and 56 grams in his steak for a total of 9 + 21 + 56 = 86 grams of protein.

Question and rationale:
The question is: Antonio is preparing a meal of spaghetti and meatballs for his family. His recipe for meatballs calls for 1/8 of a pound of hamburger per meatball. Antonio has 8 family members, including himself. If he uses 4 pounds of hamburger to make meatballs, and each member of the family eats an equal number of meatballs, how many meatballs will Antonio eat?
Step-by-step reasoning process: If one meatball is made from 1 / 8 pound of hamburger meat, then 4 pounds of hamburger meat will make 4 / (1 / 8) = 4 * 8 = 32 meatballs. 32 meatballs divided amongst 8 family members is 32 / 8 = 4 meatballs per family member.
