Option c. would be correct.

Step-by-step explanation:

Natasha purchases 3 hard cover books = $19.95 each

Price of 3 hard cover books = 19.95 × 3 = $59.85

1 book on tape = $17.43

Total purchase price = 59.85 + 17.43 = $77.28

Taxes on total purchase = 7.25% of 77.28

= 0.0725 × 77.28 = $5.60

Total amount with tax = 77.28 + 5.60 = $82.88

Natasha selects standard shipping for her purchase

For $50 upto $100 standard shipping = $6.35

this amount would be added to the total amount

Total bill = 82.88 + 6.35 = $89.23

But the company bills her credit card $91.08 for the total of the online purchase.

= 91.08 - 89.23 = $1.85 over charged for her purchase.

Natasha has been over charged by $1.85 for her purchase.
