Can you help me answer the following question please for revision purposes.

Mik Lid. is trying to determine the combination of two products, Zella and Bella that should be produced next month. Both products go through a three-stage production process: Stage I, Stage II and Stage III. At each stage, highly specialised labour time is required per unit as shown in the table below. Due to shortages in skilled labour, limited labour hours will be available for each production stage next month as indicated in the table below. Production Product Zella Product Bella Maximum Hours Stage Available Next Month Stage I 30 hours 45 hours 450 hours Stage II 40 hours 30 hours 480 hours Stage III 20 hours 15 hours 600 hours Labour is paid an hourly rate of E20 for Stage I, E22 for Stage 2 and E28 for Stage Ill. Material inputs per unit of each product are: Product Zella E5,000 and Product Bella E6,000. The Procurement Manager has confirmed that currently there is no difficulty in securing adequate supplies of material. The firm incurs annual fixed costsa) i.
