Answer 1

Answer:

Function: $y=140+25x$

Amount earned for 10 hours of work: $\ 390$

Step-by-step explanation:

Let be "x"  the number of hours worked on a project and "y" the total amount Luigi charges for a project.

Based on the data given in the exercise, you can identify that:

• $140 is a fixed amount.
• For each hour worked on the project, Luigi charges $25. This can be expressed as: $25x$

Then, the total amount he charges for a project is the sum of $140 and $25x$. This can be represented with the following function:

$y=140+25x$

To calculate the amount of money earned for 10 hours of work, you must substitute $x=10$ into the function and evaluate. Then:

$y=140+25(10)\\\\y=390$
