In 2019, Waterway sold 1100 units at $600 each, and earned net income of $84000. Variable expenses were $360 per unit, and fixed expenses were $180000. The same selling price is expected for 2020. Waterways variable cost per unit will rise by 10% in 2020 due to increasing material costs, so they are tentatively planning to cut fixed costs by $15000. How many units must Waterway sell in 2020 to maintain the same income level as 2019?
