Part 2
$3,278,000
Explanation:
Break even (units) = Fixed Cost ÷ Contribution per unit
                = $ 842,400 ÷ ($ 180 - $126)
                = 15,600 units
Assume the company's fixed costs increase by $ 141.000
Break even (units) = Fixed Cost ÷ Contribution per unit
                = ($ 842,400 + $ 141.000) ÷ ($ 180 - $126)
                = 18,212 units
Break even Revenue = 18,212 x  $ 180 =  $3,278,000
