HOW RELATIVE VALUE IS CALCULATED. 



In the calculation of relative value it is only, necessary to remem- 

 ber that so many per cent means the same number of pounds per 

 hundred, and that there are twenty hundred pounds in one ton 

 (2,000 pounds). 



With an 8 — 2 — 2 goods, which means that the fertilizer contains 

 available phosphoric acid 8 per cent, potash 2 per cent, and ammonia 

 2 per cent, the calculation is made as follows : 



. . Percentage or Lbs. Value Per Value Per Ton 



in 100 Lbs. 100 Lbs. 2,000 Lbs. 



8 pounds available phosphoric acid at 4^ cents 0.36X20= $7.20 



2 pounds potash at b\ cents 0.11 X 20= 2. 20 



2 pounds ammonia at 16i cents 0.33X20= 6. GO 



Total value 0.80X20= 16.00
