A 50 lb bag of 10-10-10 fertilizer contains how many pounds of nitrogen?

Explanation:
In a fertilizer labeled 10-10-10, each number represents the percentage by weight of nitrogen, phosphorus, and potassium, respectively. So nitrogen makes up 10% of the bag. To find how many pounds of nitrogen are in a 50 lb bag, multiply the bag weight by the nitrogen percentage as a decimal: 50 lb × 0.10 = 5 lb. So, there are 5 pounds of nitrogen in the bag. (For completeness, there would also be 5 lb of phosphorus and 5 lb of potassium in the same bag, with the remaining 70% being filler or other materials.)
