Neptune Company has developed a small inflatable toy that it is anxious to introduce to its customers. The companys Marketing Department estimates that demand for the new toy will range between 15,000 units and 35,000 units pet month. The new toy will sell for $3 per unit. Enough capacity exists in the company's plant to produce 18,000 units of the toy each month. Variable expenses to manufacture and sell one unit would be $100, and incremental fixed expenses associated with the toy would total $22,000 per month. Neptune has also identified an outside supplier who could produce the toy for a price of $1.75 per unit plus a fixed fee of $15,000 per month for any production volume up to 20,000 units. For a production volume between 20,001 and 40,000 units the fixed fee would increase to a total of $30,000 per month. Required: 1. Calculate the break-even point in unit sales assuming that Neptune does not hire the outside supplier. (Do not round your intermediate calculations.) 2. How much profit will Neptune earn assuming: a. It produces and sells 18,000 units. b. It does not produce any units and instead outsources the production of 18,000 units to the outside supplier and then sells those units to its customers. 3. Calculate the break-even point in unit sales assuming that Neptune plans to use all of its production capacity to produce the first 18,000 units that it sells and that it also commits to hiring the outside supplier to produce up to 17,000 additional units. 4. Assume that Neptune plans to use all of its production capacity to produce the first 18,000 units that it sells and that it also commits to hiring the outside supplier to produce up to 17,000 additional units. 5. If Neptune outsources all production to the outside supplier, how much profit will the company earn if it selis 35,000 units
