Work Step by Step
The first person earns $\$48,000$ per year.
The second person earns $\$3750$ per month.
There are 12 months in a year, which means that the second person earns:
$3750*12=45,000$ (dollars per year)
This means that the first person earns:
$48,000-45,000=3000$
dollars per year more than the second person.
