GPT 3.5 · Answer

To compare the total price, we need to calculate the tax and add it to the shipping and handling fee for each website.

For website A:
Price: $10
Tax: $3 * 5% = $0.15
Total price: $10 + $3 + $0.15 = $13.15

For website B:
Price: $9
Tax: $3.50 * 10% = $0.35
Total price: $9 + $3.50 + $0.35 = $12.85

For website C:
Price: $10
Tax: $0
Total price: $10 + $3 + $0 = $13

For website D:
Price: $11
Tax: $0
Total price: $11 + $2.50 + $0 = $13.50

Based on these calculations, the website with the lowest total price is website B, with a total price of $12.85.
