Question 67443: The ACT Assessment is a college entrance exam taken by about 60% of college-bound students. The national average score was 20.7 in 1993 and rose to 21.0 in 2001. Find the percent increase. (Round to the nearest hundredth of a percent.)
I'm so stumped here. I've tried so many things that i'm completely blank as how to set this up. My last attempt was : 60% � 20.7 & 60% � 21.0
I then multiplied all by 100 : 6000 � 2070 & 6000 � 2100
I show a difference of : 8070 - 8100 = 30

----------------
The increase is 21-20.7= 0.3
The percent increase = 0.3/20.7
=0.01449..
=1.45%
