配方组成:

$0.02 1/2 per lb=$ 0.63
sodium perborate/75 lb @
0.16 per lb=12.00
0.16 per lb=$ 12.63
total/100 lb
soda ash/25 lb @

配制方法:

if 100 lb cost $ 12.63, 1 lb will cost $ 12.63 divided by 100 or about $0.126, assuming no loss.
always weigh the amount of finished product and use this weight in calculating costs. most compounding results in some loss of material because of spillage, sticking to apparatus, evaporation, etc. costs of making experimental lots are always high and should not be used for figuring costs. to meet competition it is necessary to buy in large quantities and manufacturing costs should be based on these.
