question 75

Multiple Choice

The table below shows hypothetical per- minute cell phone charges for "pay- and- talk" service over several years. $$\begin{array} { | l | l | } \hline 2008 & 0.55 \\\hline 2009 & 0.50 \\\hline 2010 & 0.40 \\\hline 2011 & 0.35 \\\hline 2012 & 0.25 \\\hline\end{array}$$ TABLE 2- 2
-Refer to Table 2- 2.Assume that 2008 is used as the base year,with the index number = 100.The value of the index number in 2011 is calculated as follows:

• A)0.55/0.35 = 1.57
• B)(0.55/0.35)× 100 = 157.14
• C)(0.35/0.55)× 100 = 63.64
• D)0.35 × 100 = 35
