Each year in the United States nearly 5.4 billion pounds of discarded carpet end up in land fills. In response to this situation, the carpet manufacturer has decided to start a take-back program whereby obsolete carpet is reclaimed at the end of its useful life (about 7 years). The remanufactured carpet will then be recycled into the company's supply chain. The out-of-pocket (variable) cost of recycling is $1.00 per square yard of carpet, and the remanufactured carpet can be sold for $2.50 per square yard. If the recycling equipment costs $0.8 million and has no market value at the end of its eighteight-year life, how much carpet must be remanufactured annually to make this a profitable undertaking The company's MARR is 13?% per year.
