1) Four different products are manufactured in a factory. Sales figures and required labor-hours are given in the table below. Suggest a simple way to compute the production labor-hour requirements of an aggregate unit (an imaginary aggregate product) for this example. Product Required Labor-Hours YTX 15.0 YWW 8.5 REQ 4.5 RWS 6.0 Unit Cost (TL) 390 245 110 275 Annual Sales 12,500 units 8,000 units 20,000 units 14,000 units a) (10pts) Compute the requirements of an aggregate unit (an imaginary average product) based on labor-hours. b) (10pts) Compute the requirements of an aggregate unit (an imaginary average product) based on unit cost. c) (10pts) Which of the computations given in part-(a) and part-(b) will be more useful for planning purposes.
