To produce her cakes professionally, Mari realizes that she will need to invest in some equipment, such as a mixing machine. She plans to buy her ingredients in large quantities to get the best price. She thinks that at the start, she will take orders for 40 cakes per month, so she calculates how much the ingredients for this will cost per month. She will also need cake tins and cake boards in various sizes, as brides all want different types and sizes of cakes. She plans to deliver the cakes to her customer’s homes, as she does not have a shop and she does not want customers calling to her home. Lastly, she will need to make some money for marketing, which she plans to do using posters that will show photographs of her best cakes and by getting some leaflets printed.
