Johnson Limited manufactures and sells highly faddish products directed toward the preteen market. A new product has come onto the market that the company is anxious to manufacture and sell. Enough capacity exists in the company's plant to manufacture a maximum of 35,000 units of the new product each month. Total fixed costs (both manufacturing and non-manufacturing) will amount to $60,000 per month. The company's controller projects an operating loss of $15,000 if the company manufactures and sells 30,000 units of the new product per month.

The marketing department predicts that demand for the new product will exceed the maximum 35,000 units that the company is able to manufacture in its own plant. Additional manufacturing capacity can be rented from another company at a fixed cost of $20,000 per month to manufacture 50,000 units of the new product monthly. The variable costs to manufacture and sell units of the new product made in the rented facility will be higher at $3.75, due to somewhat less efficient operations than in the company's own plant. The new product, however, will sell for $4.50 per unit, regardless of where it is manufactured.

Required:

a) Calculate the monthly break-even sales for the new product in units if the company operates only in its own plant, that is, it manufactures a maximum of 35,000 units. (NOTE: If there is no break-even sales level, state so together with the supporting calculations and reasoning.)
