Anvi, the manager of a bakery, is interested in analyzing her bread$-$making process. The raw materials required for making bread are carried in inventory. Two steps are required in pre$$ paring the bread. The first is preparing the dough and baking the loaves, here referred to as bread making. The second is packaging the loaves. Due to the size of the mixers in the bakery, bread is made in batches of $100$ loaves. A batch of $100$ loaves is baked every hour. The loaves are then put into an intermediate stocking area ready for packing. Packaging needs only $0\mathrm{.}75$ hour to place the $100$ loaves in bags. The loaves are then stored, waiting for shipment

Anvi is considering buying an additional bread$-$making machine $($though not an additional packaging machine$).$ The time for each individual bread$-$making operation is still one hour per $100$ loaves. Assume that the bakery can sell all it can bake$\mathrm{.}4$

Draw flowcharts for the situations with both one and two bread$-$making machines.

When there is only one bread$-$making machine what is the capacity of the bakery per hour? What are the utilizations of the bread$-$making and packing operations?
