Hi asiannnn, and welcome to QuestionCove!
It sounds like Samantha pays $40 no matter how much she texts, but then she pays another $0.20 for each text she sends.
You can write a linear equation to represent the relationship between the number of texts and the fees per month.
To get you started, we know that if Samantha sends 0 texts, she pays $40.
If she sends 1 text, she pays $40.20,
For 2 texts, $40.40
And so on, at that steady, increasing rate.
Can you write an equation to express this?
