11-41. A carpet manufacturer in Georgia plans to expand its plant for a capital investment of $500,000. The extra capacity will permit the company to produce 400,000 yards of carpet each year during the plant’s five-year life.
Each yard of carpet will produce a revenue of $2.00, and the plant’s incremental operating expenses are expected to be $150,000 each year. Assume the expansion has no salvage value at the end of year five. If the manufacturer’s MARR is 18% per year, what is the minimum annual production rate to make the expansion a worthwhile investment?

(a) 103,400 yards

(b) 310,000 yards

(c) 154,950 yards

(d) 250,350 yards
