Key Questions to Answer Before You Launch the Business

Q1: How long will it take you to fill a rush order?

It depends on the number of dozens that the rush order requires. Assume that the order requires x dozen(s) (x∈N*) of orders, then the time of filling that order is (16+10x) minutes (assume that this order requires only one flavor). Firstly we consider the situation of a 1 dozen order. The all steps - washing and mixing ingredients (6min), spooning the cookies (2min), putting the cookies in the oven and setting the oven (1min), cooling down the cookies (5min), packing them (2min), and finally accept the payment (1min) - will take 6+2+1+9+5+2+1=26 minutes. Secondly, we consider the situation of a 2dozens order (seen in the Gantt chart followed). When I finished spooning the first dozen of cookies, at the end of min6, my roommate can start his work.

And when baking the second dozen, he can start cooling the first dozen and pack them. Assume we accept the payment after the cookies can be delivered, the total time of fill the order will be 36 min. Finally we accept the model and consider the situation of an x dozen(s) order, we can easily conclude that the total time is 16+10x minutes.

Q2: How many orders can you fill in a night, assuming you are open four hours each night?

When baking the cookies, my roommate will still be free for 2 min during which he can accept more orders. To maximize orders to fill in 4 hours, we assume that...
