A) the middle of the range is 39.5%
b) the difference between the middle and the ends of the range is ±1.5%
c) less than a majority favor change. Change seems unlikely.
To find 15% of something, you would multiply 0.15 by the number you are trying to find 15% of.
You can get the number by dividing 19.2 by 0.40
The number is 19.2/0.40 = 48
