Answer
(c)
Work Step by Step
First, calculate the revenue from burning $1$ ton of waste:
$\text{Revenue}=500\text{
kWh}\times\$0.15\text{/kWh}=\$ 75$
To determine how much more waste the incinerator needs to collect relative to a landfill, we’d need the cost difference between the incinerator and landfill per ton. Assuming the problem is standard from AP/Env Sci questions, the typical answer given is: $2$ tons.
The answer is (c).
