protein
percent ---------------- quantity
type I 55.00% ---------------- x pounds
Yype II 30.00% ------ 1900 - x pounds
Mixture 40.00% ---------------- 1900
1900
55.00% x + 30.00% ( 1900 - x ) = 40.00% * 1900
55 x + 30 ( 1900 - x ) = 76000
55 x + 57000 - 30 x = 76000
55 x - 30 x = 76000 - -57000
25 x = 19000
/ 25
x = 760 pounds 55.00% type I
1140 pounds 30.00% type II
