If the  average  of the original list of  4  numbers is  90 , then the sum of these  4  numbers is:  4 x 90 = 360    If the  4th n umber in the original list is  80 , then the sum of the  first 3  numbers in the original list is:  360 - 80 = 280    If the  first 3  numbers in the new list are the same as in the original list then the sum of these  new first 3  numbers is also:  280    If the  4th  number in the new list is  96  then the sum of the  4  numbers in the new list is:  280 + 96 = 376    Therefore, the  average  of the new list of  4 numbers  is:  376 / 4 =  94     Learn more about this  question  here  ;   https://brainly.com/question/13719557  #SPJ4
