Answer: 18 parent volunteers and 4 buses.
Step-by-step explanation: In order to solve this problem you must first calculate how many student will be going on the trip.
There are 8 classes of 20 students and 90% are attending, so the formula is 8 x 20 x .9 = 144 students are going.
Part A: If one parent needs to go for each 8 students you need to divide 144 by 8 = 18 parent volunteers.
Part B: The total people attending are 144 students, 18 parent volunteers and 4 teachers is a total 166 total attending to ride the bus. You need to divide 166 people by 44 on each bus = 166/44 = 3.7 buses, so they need to reserve 4 buses.
