. The manager of Green Daisy Inc. is in the process of deciding whether to make or buy carburetors for its power lawn mowers. If Green Daisy decides to manufacture the carburetor, it could utilize one of two manufacturing processes. The first process would entail a variable cost of $17 per unit and an annual fixed cost of $200,000, while the second process would entail variable cost of $14 per unit and an annual fixed cost of $240,000. The manager knows of three vendors who are capable and willing to provide the carburetor. Vendor A charges $20 per unit for any volume up to 30,000 units and cannot supply Green Daisys need for volume above 30,000 units due to its capacity restrictions. Vendor B offers a price of $22 per unit for a demand of 1,000 units or less and $18 per unit for each unit above the 1,000 units. Vendor Cs price is $21 per unit for the first 1,000 units and $19 per unit for any additional units. The manager is unsure about what the demand is going to be for power lawnmowers. d) Determine the range for which each alternative is best.
