The new business plan

This piggery has a nice floor plan and the rooms were large enough for a commercial occupancy. So we decided to help for a fast reopening. How to get the most out of this piggery? Again with mother pigs and piglets or only by fatten piglets?

My friend is accountant and he is making a plan. He adviced: only fatten piglets up to 90 days. How many piglets do we can feed? How many can we sell for a constantly income monthly? The way to answer this important questions was to know: How many piglets we can put in every room?

As a summary of all rooms we count: 62 piglets are possible in this piggery. A nice number as we want fatten them for maximum 90 days or 3 month. He devided 9 rooms by 3 month and then he teached us, how to think in units.
