![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](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F25a04a52-eee0-4f18-a3d1-babb6dd56b4f%2Fee19b8fd-4760-4aa9-bb85-77c0e4383fed%2Fi1cex3d_processed.jpeg&w=3840&q=75)
