70 GEOWING CEOPS 



2. If, in the preceding problem, the cost of preparing the 

 land and cultivating the cotton was $15 per acre, fertilizer 

 $6.50 per acre, picking 50$ -per hundred, and ginning, bag- 

 ging, and ties $1.60 per bale, what was the net cost per 

 100 Ib. of raising the cotton ? 



3. If seed cotton yields 40% lint when ginned, how 

 many pounds of cotton in the seed will it take to make a 

 520-pound bale, including 20 Ib. for bagging and ties ? 



4. A 30-acre field of cotton produced 1155 Ib. of seed 

 cotton per acre. If the ginned cotton yielded 33 J% lint, 

 how much was the cotton worth at 12|$ per pound? 



5. At an experiment station land that was plowed 8 in. 

 deep yielded 1160 Ib. of seed cotton per acre, and land plowed 

 4 in. deep yielded 950 Ib. If the ginned cotton yielded 35% 

 lint, and was worth 12$ per pound, and the seed was worth 

 90$ per hundred, what was the value of the deep plowing 

 per acre ?
