Luca works as a bagger at a local grocery store. His normal rate is $12 per hour for every hour worked up to 40 hours per week. If he works overtime, he earns $18 for every hour he works between 40 and 55 hours a week. Which interval(s) are used for the domain for the graph?(1 point)

Question

Responses

0≤h≤40; 40<h≤55

0≤h≤40; 0≤h≤55

0≤h≤55

Answer 1

The appropriate intervals for the domain of the graph, given Luca's pay structure, are:

0 ≤ h ≤ 40; 40 < h ≤ 55

This reflects that he earns his normal hourly rate for hours up to 40, and a higher overtime rate for hours worked between 40 and 55. Therefore, the first response is the correct choice:

0≤h≤40; 40<h≤55
