Answer:
The range of values from one job is between $50 and $650.
Step-by-step explanation:
An electrician charges y amount to work x hours on a job. The electrician charges a $50 service fee and $30 per hour.
This means that his earnings in a job can be modeled by the following function:
[tex]y = 30x + 50[/tex]
The electrician works maximum of 20 hours on any job. What is the range of values for one job?
Minimum, he works 0 hours, and earns:
[tex]y(0) = 30(0) + 50 = 50[/tex]
Maximum, he works 20 hours, and earns:
[tex]y(20) = 30(20) + 50 = 650[/tex]
The range of values from one job is between $50 and $650.
