Martin Enterprises needs someone to supply it with 125,000 cartons of machine screws per year to support its manufacturing needs over the next five years, and youve decided to bid on the contract. It will cost you $910,000 to install the equipment necessary to start production; youll depreciate this cost straight-line to zero over the projects life. You estimate that, in five years, this equipment can be salvaged for $85,000. Your fixed production costs will be $485,000 per year, and your variable production costs should be $17.35 per carton. You also need an initial investment in net working capital of $90,000. Assume your tax rate is 21 percent and you require a 12 percent return on your investment.

Assuming that financial breakeven needs an annual OCF of $252,672.79 and annual depreciation is $182,000, find the quantity of cartons per year you need to supply to break even. (Do not round intermediate calculations and round your answer to the nearest whole number.)
