To compare these two jobs, you need to have a common point. In this problem, you have to solve for the annual salary of the first job and compare it with the annual salary of the second job which is already given.
$12 per hour x 40 hours per week x 48 weeks in a year = $23,040
First job’s annual salary is $23,040
Second job’s annual salary is $22,000
Therefore, the job which pays $12 an hour pays more.
