Hammer Company proposes to invest $6.30 million in a new type of hammer-making equipment. The fixed costs are $1.30 million per year. The equipment will last for five years. The manufacturing cost per hammer is $2.50 and each hammer sells for $7.50. The cost of capital is 20 percent. Calculate the break-even (i.e., NPV = 0) sales volume per year. (Ignore taxes. Round to the nearest 1,000.)
