FREIGHT TRAINS A train with 150 freight cars is used to haul two types of grain. Each freight car can haul 97.3 tons of barley or 114 tons of corn. Let \(n\) represent the number of freight cars containing corn. Which function correctly represents the total weight the train can haul? $$ \text { A. } W=97.3(150-n)+114 n \quad \text { B. } W=97.3 n+114(150-n) $$
