Jorjia, 15, created three unique cupcake flavours for her business.
The first was bacon, banana and maple syrup pancake flavoured, the second mocha, caramel and sea salt and the third was peanut butter and cream.
"I did that because I always work with baking, it's something I enjoy doing.
"There's a humanistic side to my business. Like the cupcakes, the girls at Tauranga Girls' College are so unique and you can't judge something by what's on the outside."
The girls, with other teams from their business studies classes, had to set up stalls to sell their products.
Both teams said the market day had gone well. Jorjia's cupcakes sold out.
The teams will be part of a Skype judging panel on October 29 to determine the overall winner. First prize will be a trip to Wellington with their teacher to explore the city during the day and collect the Start Up Competition trophy at the Young Enterprise Scheme National Awards dinner.
Another Girls' College team placed in the top 10.
"Lucy's Lemonade", comprising Lucy Ketel, Tessa Catley, Jessica Wilson and Emily Couper, won an $80 voucher.
