Let x equal the number of FGH supermarkets in the US. Then the number of FGH supermarkets in Canada is x - 22. If there are 84 supermarkets total, then x + (x - 22) = 84, or 2x - 22 = 84. Now let's solve for x. If we add 22 to both sides, we have 2x = 106. Dividing both sides by 2, we have x = 53. Thus, there are 53 FGH supermarkets in the US. Choice (D) is correct.
