Final answer:
A negative price implies the seller pays the buyer, Permian Basin firms produce natural gas as a byproduct of oil, impacting the coal industry.
Explanation:
A negative price means that the seller has to pay the buyer 25 cents so that the buyer agrees to receive the product. Firms in the Permian Basin continue producing natural gas because it is a byproduct of producing oil, and as long as oil is profitable enough to cover the price of disposing of the natural gas, they will continue production. The coal industry and employment in that sector have been impacted by the decrease in demand for coal due to the rise of inexpensive natural gas production.
