Answer 2

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 :)
