 October, 6,000 pounds at 27 cents per pound 

 November, 5,400 pounds at 27.5 cents per pound 

 December, 5,100 pounds at 28 cents per pound 



This problem is worked as follows: 



January, $.30 X 5,000 = $1,500.00 



February, $.305 X 4,900 = $1,494.50 



March, $.31 X 5,100 = $1,581.00 



April, $.29 X 5,500 = $1,595.00 



May, $.25 X 9,000 = $2,250.00 



June, $.23 X 12,000 = $2,760.00 



July, $.24 X 10,000 = $2,400.00 



August, $.25 X 8,000 ^= $2,000.00 



September, $.26 X 7,000 = $1,820.00 



October, $.27 X 6,000 = $1,620.00 



November, $.275 X 5,400 = $1,485.00 



December, $.28 X 5,100 = $1,428.00 



83,000 $21,933.50 

 $21,933.50 -^ 83,000 = $.26426, average price per pound for the y?ar

COMPUTING THE AVERAGE PERCENTAGE OF FAT IN THE MILK OF 



A HERD 



Problem 16: 

 Compute the average test of fat of this herd: 

 Brownie 20 pounds milk testing 4.2 per cent fat 

 Spot 50 pounds milk testing 3 per cent fat 

 Red 20 pounds milk testing 4.5 per cent fat 



Nancy 10 pounds milk testing 5 per cent fat 

 Lucy 40 pounds milk testing 3.5 per cent fat 



This problem is solved as follows: 



Brownie 20 X .042 = .84, number of pounds fat 

 Spot 50 X .03 = 1.50, number of pounds fat
