Let x be the pre-tax bill for their meal.
The sales tax is x * 5.5% = 0.055 * x.
The tip is 0.15 * x.
The total amount paid is x + 0.055x + 0.15 * x = $40.
The total amount can be written as 1.205 * x = $40.
Thus, the pre-tax bill for their meal is x = $40 / 1.205 = $33.1955 (approximated to the nearest cent).
Therefore, the pre-tax bill for their meal was approximately $33.20. Answer: \boxed{33.20}.
