Assuming Fancy Millwork is considering adding another line of product bookshelves (keeping the Cabinet production constant at 800 units). Adding this line will require hiring a different type of worker which costs the company $15/hour. Fancy Millwork estimated each unit takes 30 hours of labor, and $1,500 direct materials. This line is estimated to incur additional fixed MOH $466,250 for the year, and variable costs/expenses per unit are the same as the Cabinet product line. This bookshelf product line shares the fixed period costs/expenses with the Cabinet line. Fancy Millwork estimated sales price of each bookshelf would be $3,000. How many units should the company sell to make adding the additional line economically feasible/attractive (round to the closest integer)?
