The problem is below. Questions are in the attachment.

AccuMeter manufactures and sells its only product (Z1) in lot sizes of 500 units. Because of this approach, lot (batch) level costs are regarded as variable for CVP analysis. Presented is sales and cost information for the year 2014:

Sales Revenue (50,000 units at $45)…………………………… $2,250,000
Direct Materials (50,000 units at $12)………………………….$600,000
Processing (50,000 units at $18)………………………………….$900.000
Setup (100 lots at $200)…………………………………………………$200,000
Batch movement (100 lots at $400)……………………………$40,000

Order filling (100 lots at $200)……………………………………..$20,000
Fixed manufacturing overhead ……………………………………$800,000
Fixed selling and administrative…………………………………..$300,000

d. Management is contemplating introducing a limited number of specialty products. One product would
sell for $65 per unit and have direct materials cost of $17 per unit. All other costs and all production and
sales procedures will remain unchanged. What lot (batch) size is required for a contribution of $700 per
lot?
