A train consisting of 50 cars and one locomotive weighs a total of 4725 tons. The locomotive weighs 125 tons. All of the cars have the same weight. Find the weight (in tons) of one car.
Let 50x = the weight of all 50 of them
125 = the weight of the locomotive
4725 = the weight of everything (cars and locomotive)
Can you solve this equation to find the weight of one car? Just subtract 125 from both sides, then divide both sides by 50.
