Answer:

$563.89:  total cost of the banquet

Step-by-step explanation:

Here we can to find the total cost, including tax and tip, by adding 9.25% and 18% together first.  We obtain 17.25%, which translates into the decimal fraction 0.1725 and results in the amount added to the original cost, $480.93.  The result is added to $480.93:  

1.0000($480.93) + 0.1725($480.93)  =  $563.89

A shortcut would be to find the total cost, including the original $480.93 and the additional 17.25%, by multiplying $480.93 by 1.1725:

1.1725($480.93) = $563.89:  total cost of the banquet
