Answer:
Part 1
9,000 units
Part 2
$1,575,000
Explanation:
Break even point is the level of activity where a company makes neither a profit nor a loss.
Break-even point in units = Fixed Cost ÷ Contribution per unit
                     = $315,000 ÷ ($175 - $140)
                     = 9,000 units
Break-even point in sales dollars = Fixed Costs  ÷ Contribution margin
                            = $315,000 ÷ ($35/$175)
                            = $1,575,000
