Fernando Shepherd · Answer 1

Equation: b = 0.15s

independent variable - a. number of texts sent (because it's the variable that isn't affected by the any other variables and hence is independent)

dependent variable - c. total amount charged for texting (because it depends on the independent variable)

constant (not a question, but just to let you know) - charge per text (because it doesn't not change and hence is constant)
