Calculating Dividends. 197 



say 15 cents, the value of each 100 Ibs. of milk of differ- 

 ent quality is found by multiplying its test by 15. If the 

 average tests of the different patrons' milk vary from 3 

 to 5 per cent., the relative- value table would be as 

 follows: 



3.0Xl5=45c. per 100 Ibs. 



3.1Xl5=46.5c. " 



3.2xl5=48c. " 



3.3Xl5=49.5c. " 



3.4xl5=51c. " 



3.5xl5=52.5c. " 



3.6Xl5=54c. per 100 Ibs. 

 3.7Xl5=55.5c. " 

 3.8Xl5=57c. " 



3.9X15-58.5C. u 

 4.0Xl5=60c. " 



etc. 



By continuing this multiplication, or adding the mul- 

 tiplier each time for each tenth of a per cent, up to 5 per 

 cent, of fat, a table is made that can be used for calcu- 

 lating the amount due per 100 Ibs. of milk, at this price 

 per pound, and the weight of milk delivered by each 

 patron is multiplied by the price per 100 Ibs. of milk 

 shown in the table opposite the figure representing his test. 



Example: A patron supplies 2470 Ibs. of milk, testing 3.2 

 per cent, of fat; price per pound of fat, 15 cents; he should then 

 receive 24.70X.48=$11.85 (see above table). Another patron 

 delivering 3850 Ibs. of milk testing 3.8 per cent, will receive, at 

 the same price per pound of fat, 38.50X.57=$21.94. 



The relative value tables in the Appendix give the 

 price per 100 Ibs. of milk testing between 3 and 6 per 

 cent, fat, when the price of three per cent, milk varies 

 from 30 to 90c. per 100 Ibs. In using the tables, first 

 find the figure showing the price which it has been de- 

 termined to pay for 100 Ibs. of milk of a certain quality, 

 say 3 or 4 per cent. -milk; the figures in the same vertical 

 column then give the price to be paid per 100 Ibs. of 

 milk testing between 3 and 6 per cent.
