Sofia is a full-time student and works part time as a babysitter for three families in her college town. She consistently works five hours a week, but some weeks she is able to work more hours. She has a $7,500 student loan but doesn't plan on making payments toward that until she graduates. Sofia has basic living expenses like rent, utilities, gas, car insurance, etc. She wants to start investing her money for the future. She also wants to purchase a new laptop for school. Unfortunately she never knows what her monthly income will be due to her irregular work schedule. What advice can you give her to help her meet her goals? Should Sofia purchase a new laptop? Why or why not? Should she pay off her student loan first or start investing
