ExplanationA) Simply put in a row from in an increasing order the % : 24.1, 40.0, 56.9, 62.0, 67.6, 70.0, 40.7, 72.7, 76.8. Now the median of a series of odd numbers is the middle number. hence, 67.6 %. A is the answer.

B)This is tricky: whenever in the stimulus is said something we assume that in the question - even hidden to our look - there something. Not always is true.

1) total tax revenue: nowhere in the stem is mentioned or in the graphs. A is wrong

2) Price per gallon is not mentioned. B is wrong

3) In the second graph, the Gasoline revenue 20.4 is more than 3 times the tobacco revenue 5.6.

C is true.C) This is very tricky. We need to read very carefully the entire stem. Gasoline Taxes are 20.4 and Income taxes are 28.6. We need to know the difference as % 28.6-20.4 = 8.6/28.6 = 30.0 %

D) Very tricky as well

Here we need to look at both graphs: first point out that gasoline tax is 20.4 of 170 billion, which means we do have around 34 billion. Now : in the first graph gasoline sales were 70.7. This % 70.7 of 34 billion = around 50 billion. E is the answer.

Hope is clear. Ask further whether not.

Regards
