The Table Below Shows Hypothetical Tuition Costs at a Canadian

The table below shows hypothetical tuition costs at a Canadian university. $$\begin{array} { | c | c | } \hline \text { Year } & \text { Tuition } \\\hline 2008 & \$ 5000 \\\hline 2009 & \$ 5050 \\\hline 2010 & \$ 5100 \\\hline 2011 & \$ 5150 \\\hline 2012 & \$ 5200 \\\hline\end{array}$$ TABLE 2- 1
-Refer to Table 2- 1.Assume that 2008 is used as the base year,with the index number = 100.The value of the index number in 2010 is calculated as follows:

A) 5100/5000 = 1.02
B) (5100/5000) × 100 = 102
C) 5100/5100 = 100
D) (5000/5100) × 100 = 98
E) 5000/5100 = 0.98
