Answer:
m<A: 62
m<B: 54
Step-by-step explanation:
180 - 116 = 64
3x - 13 + 2x + 4 + 64 = 180
5x + 55 = 180
5x = 180 - 55
5x = 125
x = 25
m<A:
3x - 13
3(25) - 13
62
m<B:
2x + 4
2(25) + 4
54
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.
