Answer: Option B.
Step-by-step explanation:
Given the system of inequalities:

The solution of the system of inequalities is the region between the parabolas. This region is: below the parabola
and above the parabola 
Then, if a point is a solution of the system, then it must be in the region between this parabolas.
You can observe in the figure attached that the point that is in this region is the point (2,6), therefore, the answer is the option B.
15.2 divided by 9.5 equals 1.6 pounds each pound of rye dough
To find the tax rate, you would need to find that 8 is 8/82≈.0976, or 9.76% of 82. Then use that to multiply by 123, which would be $12.
Another way is that you realize 82 is 2/3 of 123, so the tax would be 2/3 of what tax for $123 would be. So 8=2/3(x), and x=12.
