Last year, Casey grew fresh vegetables, which she sold at her local farmers market, but this year, Casey did not plant any vegetables and went to work at a bank instead. Which of the following best explains Casey's career change?

While she grew and sold vegetables, Casey did not make enough money to cover her expenses and make some profit. This is the most probable reason why she opted for a career change and took a different job. Casey's opportunity costs of gardening exceeded the money she would earn from working at a bank.
