With the automated machine, production and sales are expected to increase by 6,800 units per year for the next 10 years. Selling price will remain $95 per unit. Total variable cost is still $57 per unit, but the annual fixed costs will increase by $68,000 All cashflows are assumed to occur at the end of each year.
