mmmmhhh?
if the mean is 48, that means the average number was 48
so we divide each by 48, then subtract 35 to get 1
so what is the average of a bunch of 1's ??
then new mean is 1
illustration: lets simplify the question
you are given the numbers 12, 18, and 24
the mean would be 18
let's divide each number by 2, then subtract 3
12 ---> 3
18 ---> 6
24 ---> 9
new average (mean) = 6
