Suppose each EMU student generates one bag of trash every 3 days. Each EMU dumpster can hold about 60 bags of trash. The trash is hauled on train cars, each which can hold 40 dumpsters. How many train cars full of trash will 900 EMU students fill in a 14 week semester?

(1bag/3student-days)(1dumpster/60bags)(1train car/40dumpsters)(900students)(98days)

= (900)(98) / (3)(60)(40)

= 12.25 train cars   or   12 1/4 train cars
