The company is considering a purchase of equipment that would reduce its direct labor costs by $114,088 and would change its manufacturing overhead costs to 30% variable and 70% fixed (assume total manufacturing overhead cost is $394,920 as above). It is also considering switching to a pure commission for its sales staff. This would change selling expenses to 90% variable and 10% fixed (assume total selling expense is $263,280, as above). Compute (1) the contribution margin and (2) the contribution margin ratio, and recompute (3) the break-even point in sales dollars.

Contribution margin =?

Contribution margin ratio=?

Break-even point in sales=?
