Q$8.$ Gayle's Glassworks makes glass vases. Materials cost $$1$ per vase, and the glass blowers are paid a wage rate of $$28$ per hour. A glass blower blows $10$ vases per hour. Fixed manufacturing costs for vases are $$28,000$ per period. Period $($nonmanufacturing$)$ costs associated with vases are $$10,000$ per period and are fixed.

a$)$ Graph the fixed, variable, and total manufacturing cost for vases

b$)$ Assume Gayle's Glassworks manufactures and sells $5,000$ vases in this period. Its competitor, Flora's Flasks, sells vases for $$10$ each. Can Gayle sell below Flora's price and still make a profit on the vases?

c$)$ How would your answer to requirement $2$ differ if Gayle's Glassworks made and sold $10,000$ flanges this period? Why? What does this indicate about the use of unit cost in decision making?
