One bag of urea containing 46 percent nitrogen weighs 25 kg. How many bags have to be purchased for fertilizing a field of 41003 square meters if the nitrogen dose is 50.0 kg per hectare?

Correct answer:

n =  18

Step-by-step explanation:

S=41003 m2 ha=41003:10000  ha=4.1003 ha  m=50 S=50 4.1003=205.015 kg 0.46 m1=m m1=m/0.46=205.015/0.46=9241003=4459263445.6848 kg  n=m1/25=445.6848/25=18
