Luigi is an urban planner. As an independent contractor, he charges $140 fee plus $25 per hour for each contract with the city. Write a function to represent this scenario where y represents the total amount he charges for a project and x represents the number of hours worked on a project.
The function representing the scenario can be written as:
y = 140 + 25x
In this equation, y represents the total amount Luigi charges for a project, and x represents the number of hours worked on that project. The fixed fee of $140 is added to the product of the hourly rate ($25) and the number of hours worked (x).
what is the amount earned after 10 hours of work?
To calculate the amount earned after 10 hours of work, we can substitute the value x = 10 into the function:
y = 140 + 25x
y = 140 + 25(10)
y = 140 + 250
y = 390
Therefore, the amount earned after 10 hours of work is $390.
