The best estimate for x can be determined by solving the equation 21x + 1,998 = 2,243.
Subtracting 1,998 from both sides of the equation gives 21x = 245.
Then, dividing both sides of the equation by 21 gives x = 11.6667.
Since none of the given answer choices match this solution, it is not possible to determine the best estimate for x using the provided options.
