Option c.

Step-by-step explanation:

Glenda purchased 4 picture frames for $12.95 each and 4 mats for $5.89 each.

Cost of 4 picture frames = 12.95 × 4 = $51.80

Cost of 4 mats = 5.89 × 4 = $25.56

Total purchase = $51.80 + $25.56 = $75.36

taxes paid by Glenda = 6.5%

Total purchase price with tax = 75.36 +(6.5% × 75.36)

                                                 = 75.36 +(0.065 × 75.36)

                                                 = 75.36 + 4.8984

                                                 = $80.2584 ≈ $80.26

Shipping charges $50 up to $100 for express shipping = $8.20

So, her total bill would be = 80.26 + 8.20 = $88.46

Glenda was charged for the total of the online purchase = $91.86

She has been over charged = 91.86 - 88.46 = $3.40

Option c. Glenda has been over charged by $3.40 for her purchase.
