Background

Your friend intends to start a business selling bubble tea. He knows that you are currently taking a course in Business Economics. He has some questions regarding his new business and would like to seek your advice.

The bubble tea store will be situated at a rented HDB shop house unit with a floor area of 20 square meters. The store will only be selling one type of bubble tea which is the generic bubble milk tea. To set up the bubble tea business, your friend would need a fridge for storing of raw materials, a cooker, two mixers and a sealer to seal the cups. Currently your friend plans to run the store on his own and does not require any helper.

Within the vicinity of the rented HDB shop, there are a number of stores selling different beverages in addition to the 6 other stores selling bubble tea of different flavors. Besides the residents around the area, the other main group of customers is the school children from the nearby primary schools with an upcoming secondary school. With the recent conflict in Ukraine and the disruption to global supply chain, your friend has complained that it is becoming more difficult to obtain raw materials for bubble tea to operate his business.
