Question

I hire an assistant to help me with my grading. I agree to pay her $50 per week, plus $2 for each exam she grades. Write an equation that describes how much she earns in a week. Make sure you declare your variables!

Answer 1

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:

`w=50+2e`
