A group of biologists studied the nutritional effects on rats that were fed a diet containing 10% protein.The protein was made up of yeast and corn flour.By changing the percentage P (expressed as a decimal)of yeast in the protein mix,the group estimated that the average weight gain g (in grams)of a rat over a period of time was given by g = + 200P + 20.What percentage of yeast gave an average weight gain of 70 grams?
A) 50%
B) 60%
C) 65%
D) 70%
E) 80%
