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

0≤h≤40; 0≤h≤55

Answer 1

The appropriate intervals for the domain of the graph, based on the description provided, are:

0 ≤ h ≤ 40; 40 < h ≤ 55

This is because Luca earns his normal rate of $12 per hour for hours worked up to 40, and for hours worked between 40 and 55, he earns an overtime rate of $18 per hour. Therefore, the intervals that capture these conditions are correct.

So the answer is: 0 ≤ h ≤ 40; 40 < h ≤ 55
