A certain company reported that the revenue on sales increased 40 % from 2000 to 2003, and increased 70 % from 2000 to 2005. What was the approximate percent increase in revenue for this store from 2003 to 2005?
Choose the correct option:
A) 50 %  B) 40 %  C) 35 %  D) 32 %  E) 21 %
Assume the revenue in 2000 to be 100. Then in 2003 it would be 140 and and in 2005 170, so from 2003 to 2005 it increased by (170-140)/140=30/140=~21%.   Answer: 21 %.
