Mila is working two summer jobs, making $10 per hour washing cars and $11 per hour landscaping. Last week Mila worked a total of 14 hours and earned a total of $145. Write a system of equations that could be used to determine the number of hours Mila worked washing cars last week and the number of hours she worked landscaping last week. Define the variables that you use to write the system.
