You hire an assistant to help you grade exams. The assistant gets paid $50 per week plus $2 for each exam graded.

Let "e" represent the number of exams the assistant graded, then her earnings for grading e exams can be expressed as "2e"

Let "w" represent the assistant's total earnings in a week, this is, the weekly fee ($50) plus the fee per exam graded (2e), you can express her total earnings per week as follows:

[tex]w=50+2e[/tex]
