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.

Answer 1

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).

Answer 2

what is the amount earned after 10 hours of work?

Answer 3

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.
