income of $$40000.$ Variable expenses were $$400$ per unit, and fixed

expenses were $$260000.$ The same selling price is expected for $2017.$

Crane$$s variable cost per unit will rise by $10\%$ in $2017$ due to

increasing material costs, so they are tentatively planning to cut

fixed costs by $$10000.$ How many units must Crane sell in $2017$ to

maintain the same income level as $2016?2417322210004833$
