Explain simply why 90 is the correct answer to: There are 6 people going on an airplane trip. They each have 5 bags of luggage. Each of their bags weighs the maximum weight allowed, 50 pounds. The airplane can hold a total luggage weight of 6000 pounds. How many more bags at maximum weight can the plane hold?. Explanation:
Each person brought 5 bags * 50 pounds per bag = 250 pounds per person. There are 6 people * 250 pounds per person = 1500 pounds of luggage on the plane. The plan can hold 6000 pounds - 1500 pounds = 4500 pounds of luggage space left. The plane can hold an additional 4500 pounds / 50 pounds per bag = 90 pieces of luggage.
