TOEIC ETS

M: How can I help you? W: Hello. I'm doing some renovating at home. I'll be replacing all the pipes, the sink, and the bathtub in my bathroom. The pipes are lead, and the other fixtures are cast iron. They're all very heavy. M: That's no problem. We'll bring a dumpster out to your home, you fill it up with scrap, and then we'll come remove it when you're ready. W: OK. So, is payment determined by the number of days I keep the dumpster? M: No, we'll weigh it before and after and charge you accordingly. Here's a list of charges by kilogram.
