Answer:
Jim will earn more money than Allison.
Step-by-step explanation:
The average salary for someone with a 4 year college degree is $51,000 (2019), that doesn't mean that Jim will earn that money, he might earn more or less, but it is a useful parameter. The average salary of someone who just finished high school is $28,000 (2019).
If we compare both average national salaries, we can assume that Jim will earn much more than Allison.
