Final answer:
Luis's new job with a salary of $45,000 a year will pay more per month compared to his current job. It pays $3,750 per month, which is $450 more than the $3,300 he currently earns monthly.
Step-by-step explanation:
To determine whether the new job with an annual salary of $45,000 pays more or less per month than Luis's current job that pays roughly $3,300 a month, we shall calculate the monthly income from the new job.
Luis's annual salary at the new job can be divided by 12 to find the monthly income:
$45,000 / 12 months = $3,750 per month
Comparing this with his current monthly income of $3,300:
$3,750 (new job) - $3,300 (current job) = $450
This shows that the new job will pay $450 more per month than his current hourly job. Therefore,
A. The new job will pay more.
