Respuesta :

In order to determine the correct answer, we need to confirm it first by making the solution below:
Costs: $89.95 = New Lamp
            $239.99 = Comforter
            6 3/5% = Sales Tax (convert this to decimal and we get 6.6%)
            $351.72 = Total amount the Chang's paid
Let's get the total costs first which is $329.94
6.6% of 329.94 is $21.78
The total cost with the tax would be $351.72.
Therefore, the Chang's paid the correct amount. The correct answer would be option D. The Chang's family paid the correct amount for their purchases.
