Between 2000 and 2010, the percentage of fatal automobile accidents due to speeding decreased by 34% to 16%. What percentage of fatal automobile accidents were due to speeding in 2000?
I would think that in 2000, the percentage was 24.2 % then it decreased by 34% to 16%
If the problem had stated the death rate had decreased by 34 percentage points I would answer differently...
This is the reason one should be wary of people using percentages to back their opinions....they can be very deceptive....
