Luigi is an urban planner

Math Feb 02, 2021

Luigi is an urban planner. As an independent contractor, he charges a $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 her charges for a project and x represents the number hours worked on a project.

Expert Solution

The answer is y = 140 + 25x

Luigi charges $140 no matter what, but the $25 per hour fee depends on the number of hours it takes to complete the project. So, if it takes Luigi 2 hours, for example, then he will charge $190:

y = 140 + 25(2)
y = 140 + 50
y = 190
