Write the function rule for the table.
Let $m=$ number of months and $t=$ total price of cell phone service.
\begin{tabular}{|c|c|}
\hline $\begin{array}{c}\text { Number of } \\
\text { months }\end{array}$ & $\begin{array}{c}\text { Total price of cell } \\
\text { phone service }\end{array}$ \\
\hline 1 & $\$ 35$ \\
\hline 2 & $\$ 70$ \\
\hline 3 & $\$ 105$ \\
\hline 4 & $\$ 140$ \\
\hline
\end{tabular}
Answer
\(\boxed{t = 35m}\) is the final answer.
Step 1 ：The given table shows a linear relationship between the number of months and the total price of cell phone service. For each additional month, the total price increases by $35.
Step 2 ：This suggests that the function rule is \(t = 35m\), where \(m\) is the number of months and \(t\) is the total price of cell phone service.
Step 3 ：\(\boxed{t = 35m}\) is the final answer.
