Question 1131754: In an nutrion experiment, a biologist wants to prepare a special diet for the experimental animals. Two food mixes A and B are available. If mix A contains 20% and mix B contains 10% Protein, What combination of each mix will provide exactly 20 grams of protein ? Let x be the amount A used and let y be the amount B used. Write a linear equation related x,y and 20. Graph this equation for x values between 0 and 200.

You can put this solution on YOUR website!
x grams of mix A
y grams of mix B
20 grams protein wanted

0.20x%2B0.10y=p, for grams of PROTEIN


0.2x%2B0.1y=20, good equation to use.

Better:
2x%2By=200
y=200-2x
highlight%28y=-2x%2B200%29
Note, you must use only from quadrant 1.
