Total , 



545-35 



This gives a total of 545.35 lbs. of fat delivered. With an overrun of 

 20% there would be obtained from the 545-35 lbs. of fat, 654.42 pounds 

 of butter (545.35 X 1.20 = 654.42), which at 32 cents per pound would 

 equal $209.41 ($.32 X 654.42 =$209.41). Let us assume that the cost 

 of making the butter was $10. Subtracting this from $209.41, there is 

 left $199.41 to pay for the fat ($209.41 — $10.00 = $199.41). Dividing 

 $199.41 by 545.35 we get .36565, rate to be paid per pound of fat. Answer. 



Multiplying each patron's fat by this rate will give the money to be paid 

 each one. The amounts are shown in the following table:

Note: The rate should always be carried to the fifth decimal place, and when the 

 fifth decimal place is a zero the rate should be carried to six decimal places. If 

 the rate were not so carried out, there would be a considerable amount of money 

 undivided. 



CALCULATING THE RATE ON THE FAT BASIS IN A COOPERATIVE CHEESE 



FACTORY 



Milk is frequently bought for cheese-making on a fat basis and the 

 patrons are paid according to the amount for which the cheese sells. 

 The rate is obtained in the same way as in the case of a butter factory,
