Answer:
J represents a scenario where the mixture has more than the intended volume and has the intended percent of body fat.
Step-by-step explanation:
Equation of Line A is .30x+.02y=.12(500). So it represents the total volume of butterfat (0.12*500) Otto wants in his mixture. Point J is on line A so it represents a scenario where the mixture has the intended 12% butterfat.
The Equation of Line B is x+y=500, so it represents the total volume(500mL) of the mixture Otto wants to make.
Point J located near(1100,100), which is not on line B, so it doesn't represent a scenario where the mixture has the intended amount. It represents a scenario where the mixture has a volume of a little more than 1100 +100=1200mL.
