Using the reply button post as ONE response to all topic questions then submit a quality reply to one other post. Stating good comment, I agree or I like the way you put that is not considered a quality post unless it includes reasons why. Identify each question first then your response..... Remember the focus is on the quality and detail of the comments. 1. Explain how fixed costs per unit and variable costs per unit respond to changes in volume? Be detailed in your answer. 2. What are mixed costs? How do the per-unit fixed costs respond to changes in volume? 3. Assume P's Bakery Shop has fixed costs per month of $3,000 and variable costs are 60% of sales. What amount of monthly sales allows the shop to break-even (round to nearest dollar)
