Answer:
To calculate the total cost of the party after taxes, we need to determine the tax amount and add it to the pre-tax cost.
The amount taxed is given as $64.83, and the tax rate is 8.65%. To calculate the tax amount, we can multiply the taxed amount by the tax rate:
Tax amount = $64.83 * 8.65% = $5.61
Now, to find the total cost of the party after taxes, we can add the tax amount to the pre-tax cost:
Total cost = Pre-tax cost + Tax amount
Total cost = $386.54 + $5.61
Total cost = $392.15
Therefore, the total cost of the party after taxes is $392.15.
