The maximum number of adults is 8 and children is 32 .
Step-by-step explanation:
Let the number of adults be-----------x, where x>0
Let the number of children be---------y, where y>0
Charges for an adult per trip = $18
Charges for a child per trip = $8
Total number of people a bus can carry = 40
The inequality for total number of people a bus can carry will be;
x+y ≤ 40 ...............(i)
The school can only spend $400 on the trip, thus the inequality for cost of trip will be;
$18 x + $8 y ≤ $400
18 x + 8 y ≤ 400 -----------(ii)
Using a graph tool to plot the inequalities and view the results gives the attached graph
From the graph, x= 8 and y=32
