A factory currently manufactures and sells 800 boats per year. Each boat costs $5,000 to produce. $4,000 of the per-boat costs are for materials and other variable costs, while the per-boat fixed costs (incurred on yearly rent, administrative, and other fixed costs) are $1,000. If boat orders increase to 1000 boats per year, how do per-unit costs change?
