Please help with a, b and c. As well with the graph. Thank you

Chapter 3 1. Company A makes glass flanges for scientific use. Materials cost $1 per er hour. blower blows 10 flanges per hour. Fixed manufacturing costs for flanges are $20,000. Period (non-manufacturing) costs associated with flanges are $10 per period, and are fixed. Required: a. Graph the fixed, variable and total manufacturing cost for flanges, using units (number of flanges on the x-axis). b. Competing firm sells flanges for $8.25 each. Can company A sell below its competitor's price and still make a profit on the flanges? (Note: assume company A produces and sells 5,000 flanges). How would your answer in b differ if Company A made and sold 10,000 flanges? Why? What does this indicate about the use of unit cost in decision making? c
