QuestionDefine a linear equation for the monthly cost $C$ of a cell phone plan based on data usage $d$ in GB, given $C = 21 + 5d$.

Studdy Solution
Now, we can substitute the given values into the equation. The cost per GB of data ($m$) is $5.00 and the basic monthly charge ($b$) is$21.00.
$$C =5 \cdot d +21$$This is the linear equation that models the monthly cost of the cell phone plan based on the number of GB of data used.
