Step-by-step explanation:

<em><u>C.x=86.113</u></em>
Step-by-step explanation: If you take a look at the right side of the equation, a 3 is being added to our variable <em>x</em>.
If you were going to solve this equation, you must subtract 3 from the right side and the left side to isolate our variable.
You would end up with 4 = x.
There are 4! ways to sit the boys, and 4! ways to sit the girls.
Whether the boys sit to the left or the right of the girls don't matter, since it is a circular table AND rotations are not considered distinct arrangements.
So the total number of arrangements is the product of the two, namely n=4!4!. (note: (4!)^2 or (four factorial) squared.
