Answer: d. higher-paying job has a compensating wage differential of $3 per hour.
Step-by-step explanation:
Compensating wage differential is the amount paid to a worker to entice them to take a less attractive job. In this scenario, the less attractive job is working the night shift which is what Guilherme is doing.
To compensate Guilherme for taking this job, the company is paying $25 instead of the $22 it is paying Chloe. This means that the compensating wage differential is the difference which is:
= 25 - 22
= $3
