Answer:
Sabrina's income will be greater than the classmate's now, but will be lower in the future.
Step-by-step explanation:
Since most college students focus on their study, very few of them generate a personal income during their college. This made Sabrina's income will most likely be greater than the classmate's now.
But, according from the statistic from United States' government, people who graduated college on average earned $25,000/year more compared to people who decided to work full time without a college degree. This happened because high paying positions in the country typically require applicants to have at least a bachelor degree. So in the long run, finishing college might be the better option for the future.
That's being said, this statistic is just a probability. There is still a chance that people who dropped out college able to build up their own business and generate a lot of income.
