D
Natasha has been over charged by $8.20 for her purchase.

Explanation

The books cost 3 × $19.95 + $17.43 = $77.28. Since this amount is between $50 and $100, standard shipping is $6.35, and the 7.25% tax is $77.28 × 0.0725 = $5.60 (rounded to the nearest cent). The correct total is $77.28 + $6.35 + $5.60 = $89.23, so Natasha was overcharged by $91.08 − $89.23 = $1.85. The correct choice is “Natasha has been over charged by $1.85 for her purchase.”
