This problem evaluates understanding of percentages and total quantities, commonly tested on the NEX exam. First, calculate the total number of gloves available. Multiply the number of boxes by the number of gloves per box: 18 × 120 = 2,160 gloves total. Next, determine how many gloves were used. Since 25% were used, convert 25% to a decimal (0.25) and multiply by the total number of gloves: 0.25 × 2,160 = 540 gloves used. To find how many gloves remain, subtract the number used from the total: 2,160 − 540 = 1,620 gloves remaining. Therefore, option A is correct. Option C represents the original total, not the remainder. Option D reflects incorrect subtraction, and option B results from miscalculating the percentage used. On the NEX Math Section, it is critical to identify whether the question asks for the amount used or the amount remaining before selecting an answer.
