A grocery store stock person unloads and stocks packages of water bottles. Shipments arrive several times a month, and each shipment is identical. Each shipment contains 24 six-packs weighing s pounds per package, 36 twelve-packs weighing w pounds per package, and 48 twenty-four-packs weighing t pounds per package. The total weight, T, of all of the shipments of water bottles for an entire month is given by: T = n (24s + 36w + 48t) In this equation, what is the meaning of the variable n? A-n represents the total number of water bottles for A the entire month.

B-n represents the total number of water bottles in one shipment.

C-n represents the total weight of one shipment.
