A cellular phone company charges $80 for a phone and $70 per month for its economy plan. Let \( y \) denote the total cost in dollars and \( x \) denote the number of months. Answer parts a-e.

**a.** Find the equation that expresses \( y \) in terms of \( x \).

\[ y = \_\_ \]

**b.** Determine \( b_0 \) and \( b_1 \).

\[ b_0 = \_\_, \, b_1 = \_\_ \]

**c.** Construct a table for the \( x \)-values 3, 15, and 18.

\[
\begin{array}{|c|c|}
\hline
\text{Time (months) } x & \text{Cost ($) } y \\
\hline
3 & \text{(Simplify your answer.)} \\
\hline
15 & \text{(Simplify your answer.)} \\
\hline
18 & \text{(Simplify your answer.)} \\
\hline
\end{array}
\]

**d.** Choose the correct graph of the linear equation.

- \( \bigcirc \) A. 
- \( \bigcirc \) B. 
- \( \bigcirc \) C. 
- \( \bigcirc \) D. 

**Graphs Description:**

- **Graph A**: A line passes through points approximately at \( (0, 80) \) and \( (24, 1760) \).
- **Graph B**: A line passes through points approximately at \( (0, 150) \) and \( (24, 1840) \).
- **Graph C**: A line passes through points approximately at \( (0, 80) \) and \( (24, 2800) \).
- **Graph D**: A line passes through points approximately at \( (0, 750) \) and \( (24, 2230) \).

**e.** By looking at the graph to estimate the cost for 12 months, between what two amounts will the cost fall?

- \( \bigcirc \) A. $1000 and $1500
- \( \bigcirc \) B. $2000 and $2500
- \( \bigcirc \) C. $2500
