Ответ:
Part A= 36% I got my answer by subtracting the part from the total.
Part B= The total number of sixth graders on academic teams is 124. I got this by adding the 45% and the 36% to get 81% and then add the total number of students in both schools, which was 124. So then 81% of 155 is 124.
Step-by-step explanation:
100% - 64% = 36%
45% + 36% = 81%
80 + 75 = 155
80% of 155 is 124
