Problema Solution
soybean meal is 16% protein, cornmeal is 8% protein. How many pounds of each should be mixed togeather to get 320 lb mixture that is 13% protein?
Answer provided by our tutors
Let x = amt of soy
then the total is to be 320lb, therefore:
(320-x) = amt of corn
:
A typical mixture equation:
.16x + .08(320-x) = .13(320)
.16x + 25.6 - .08 = 41.6
.16x - .08x = 41.6 - 25.6
.08x = 16
x =
x = 200 lb of soy
then
320 - 200 = 120 lb of corn

Check solution in original equation
.16(200) + .08(120) = .13(320)
32 + 9.6 - 41.6
