question 30

Multiple Choice

The table below shows hypothetical per- minute cell phone charges for "pay- and- talk" service over several years. $$\begin{array}{l}\begin{array} { | l | l | } \hline 2005 & 0.55 \\\hline 2006 & 0.50 \\\hline 2007 & 0.40 \\\hline 2008 & 0.35 \\\hline 2009 & 0.25 \\\hline\end{array}\\\text { TABLE 2- } 2\end{array}$$

• A) (0.55/0.35) × 100 = 157.14
• B) (0.35/0.55) × 100 = 63.64
• C) 0.35/0.55 = 0.64
• D) 0.35 × 100 = 35
