Explanation
The percent increase from 2000 to 2001 is:
Percent Change =\(\frac{Difference}{Original}\times 100 \%\)
Percent Change =\(\frac{20}{10}\times 100 \%=33.333333 \%\)
Now, apply a 33.33333%, or \(\frac{1}{3}\), increase to 2004’s figure. The GRE calculator cannot accept a repeating decimal; instead, divide 162 by 3 to get the amount of increase, and then add 162 to get the new profit per student in 2005: 162 ÷ 3 + 162 = 216.

Previous percent increase is 33.3% so From 2004-2005; 162*33.3 = 5394.6 then divide it by 100 we get 53.946; adding this with 162 + 53.946 = 215.9460, this is the actual per-student profit whereas we take it as 216.
Now, my question is in the main/real GRE xm do I need to put the 215.94 or just by leveling 215.94 to 216 and then put 216 as an answer. ???
