The employees of two factories, X and Y, are comparing their respective production records. Factory X has already produced 18,000 units and can produce 120 units per day. Factory Y has produced only 14,500 units but can produce 155 units per day. If d represents the number of days (that is, days during which each factory is producing its maximum number of units), which of the following equations could be solved to determine the number of days until X's total production equals Y's total production?
(A) 18,000 + 120d = 14,500 + 155d
(B) 18,000 + 155d = 14,500 + 120d
(C) (18,000 + 120)d = (14,500 + 155)d
(D) (120 + 155)d = 18,000 - 14,500
(E) (120 + 155)d = 18,000 + 14,500
