To find our answer we need to set up and solve an equation. Let the total number of guests be represented by g. The cost per guest is $13.50 Therefore the cost for all of the guests will be $13.50 × g.
To find the total cost we need to add the additional fee of $540 to cover linens and tableware.
Now we've found our equation.
Subtract 540.
Divide by 13.5
Therefore, there are 72 guests. The answer is 72. ~ Hope this helps you!
