CHEDDAR CHEESE 347 



225 Ib. milk X 30 = 6750 Ib. of milk delivered 



.37% .29% = .08% more fat retained in cheese made by B than 

 byA 



6750 (Ib. of milk) x .85 = 5737.5, approximate weight in Ib. of 

 whey 



5737.5 X .0008 = 4.59, number of Ib. more fat retained in cheese 

 made by B than by A 



If each Ib. of fat yields 2.68 Ib. of cheese, 



4.59 x 2.68 = 12.3, number of Ib. more cheese made by B than by 

 A 



$.13 X 12.3 = $1,60. Answer. 



PROBLEM 3 



Two farmers each deliver daily 385 Ib. of milk to the same cheese 

 factory. A's milk tests 3.5 per cent fat and B's tests 4.5 per cent fat. 

 If they are paid for their milk on the basis of the yield of cheese, how 

 much more will B receive than A in one month, cheese selling for 13 

 cents a pound ? 



385 Ib. milk X 30 = 11,550 Ib. milk delivered by each in 30 days 

 11,550 X .035 = 404.25, number of Ib. fat delivered by A 

 Each Ib. of fat in 3.5 % milk yields 2.68 Ib. of cheese (see table above) 

 404.25 X 2.68 = 1083.39, number of Ib. of cheese from A's milk 

 $.13 X 1083.39 = $140.84, amount that A should receive for his milk 

 11,550 X .045 = 519.75, number of Ib. fat delivered by B 

 Each pound of fat in 4.5% milk yields 2.61 Ib. of cheese 

 519.75 X 2.61 = 1356.55, number of Ib. of cheese from B's milk 

 $.13 X 1356.55 = $176.35, amount that B should receive for his milk 

 $176.35 - $140.84 = $35.51, amount that B should receive more 

 than A for his milk. Answer. 



Value of fat usually lost in whey. 



PROBLEM 4 



A cheese factory determines to make whey butter from 10,000 Ib. 

 of whey. It tests .32 of 1 per cent fat. With an overrun of 12 per cent, 

 and butter worth 25 cents a pound, compute the value of the whey 

 butter for one day. 



10,000 X .0032 = 32, number of Ib. of fat 



32 x .12 = 3.84, number of Ib. overrun 



32 Ib. + 3.84 Ib. = 35.84, number of Ib. butter 



25 cents x 35.84 = $8.96, value of whey butter for one day.
