## I seriously need help I am a freshman and I have advanced classes hint hint look above!!!

Average (mean) = (sum of all the data) / (# of data) sum of all the data = (average)(# of data) Thus for 100 students with an average of 93, sum of all data = (93)(100) = 9300 and for 300 students with an average of 75,sum of all data = (75)(300) = 22500 Therefore
