Celdrick's scribepost question 20

Q: A 30 kg bag of fertilizer is labelled 15-20-10. This means that it contains 15% nitrogen, 20% phosphorus, and 10% potassium by weight. How many kilograms of nitrogen, phosphorus, and potassium are in the bag?

Lets find out how many kilograms each ingredient is.

15% of 30= 4.5 kg

20% of 30= 6 kg

10% of 30= 3 kg

4.5+6+3= 13.5 kg

A: THERE IS 13.5 kg OF Phosphorus, Nitrogen, and Potassium in the bag.
