$500,000 is invested in processing equipment having a negligible salvage value regardless of the number of years used. Annual cost savings of $50,000 occur the first year; thereafter, annual savings increase 13% per year. Based on a MARR of 13%, solve mathematically for the DPBP. Assume a fractional number of years is feasible. Click here to access the TVM Factor Table calculator. n= years Round entry to 2 decimal palces. The tolerance is 0.02
