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....

Let the percentage of fatalities in 2000 =x, then we have:

x - .34x =.16, solve for x

x =8/33 =24.24% original percentage of fatalities in 2000.
