Answer:
For part A the answer is 18, 18 parent volunteers needed to go on the trip.
Part B The answer is 4 buses
Step-by-step explanation:
Part A explanation: there are 4 classes for each 5th and 6th grade with 20 students in each.
4*20= 80 but you would do this twice for each grade
4*20=80
add both of them which is 160 but only 90% can go so you would do
160*90%=144
But a parent volunteer is needed for every 8 students so you would do
144/8 which equals 18
Part B: you would take what you know in part A and apply it to part b.
144 studens can go, and 4 teachers are going, and 18 parent volunteers are coming
so this would be
144+4+18=166
But its calls for 1 school bus for every 44 people, so you then do
166/44=3.772
You can't do this so you round it up to 4!!
Hope this helps please mark brainliest :)
