Answer
A
did not pay enough
B
paid 3 point 1 1 dollars too much
C
paid 2 point 6 0 dollars too much
D
paid the correct amount
Explanation
The gas costs 12 × $2.89 = $34.68. The taxable items total 2 × $1.59 + $0.89 + 2 × $1.39 = $6.85, and 7.5% tax on them is about $0.51. So the total due is about $34.68 + $6.85 + $0.51 = $42.04; since Leon paid $44.64, he paid $2.60 too much.
