City 1 produces 500 tons of waste per day, and city 2
produces 400 tons of waste per day. Waste must be incinerated at incinerator 1
or 2, and each incinerator can process up to 500 tons of waste per day. The
cost to incinerate waste is $40 per ton at incinerator 1 and $30 per ton at
incinerator 2. Incineration reduces each ton of waste to 0.2 ton of debris,
which must be dumped at one of two landfills. Each landfill can receive at most
200 tons of debris per day. It costs $3 per mile to transport a ton of material
(either debris or waste). Distances (in miles) between locations are listed

the waste from both cities.
