S=weight of soybean protein, C=weight of cornmeal protein.
Total weight of each protein is 0.18S+0.19C=0.17×360=61.2 lb.
Total weight of meal is S+C=360 lb. So S=360-C.
Therefore 0.18(360-C)+0.19C=61.2, 64.8-0.18C+0.19C=61.2, 0.01C=-3.6.
Clearly we would get a negative value for C. When you look at the question you will realise that there is a larger percentage of protein in the ingredients than there is in the mixture. The expected amount of protein in the mixture should be between 18% and 19%. Please check your figures.

Answer:
Rate =interest ×100/principle ×time
=1800×100/8000×3/2
=15%
Step-by-step explanation:
First off subtract the cost of the computer from the total cost
1,220-995 = 225
Then divide 225 by 3 to get the price of each of the software
225/3 = $75
