Answer 3

range is 600 and needs to be converted to range of 100
so divide by 6
200-800 -> 33.33 - 133.33
this is 33.33 higher than desired scale
so subtract 33.33
33.33 - 133.33 --> 0-100
so formula for conversion
f(x) = x/6 - 33.33
f(684) = 684/6 - 33.33
F(684) = 80.67

Answer 4

It would be the same if you subtracted 200 first
--> 0-600
then divided by 6
-->0-100
f(x) = (x-200)/6
f(684) = 80.67
