PLEASE, can anyone help me with what to do?
Soybean meal is 18% protein, cornmeal is 9% protein. How many pounds of each should be mixed together in order to get 360-lb mixture that is 17% protein? This makes no sense to me.

ok let me write it out
Oh Thank yo so much!!!
call the amount of soybean x so the amount of cornmeal is
because they have to total 360 when you add them.
soybean is 18% protein so you will have is \[.18\times x\] protein from the soybean and also \[.09\times (360-x)\] protein from the cornmeal. you want this to be \[.17\times 360\] so set them equal and solve \[.18x+.09\times (360-x)=.17\times 360=61.2\]

i will be happy to show you how to solve this if you like. if the decimals are annoying multiply both sides by 100 to get
if not clear let me know
