It is not possible for 120 kids and 20 adults to go on the trip, but 120 students can go with a maximum of 12 adults so the expense of the trip can fall in the school's budget.
We know that tickets of the zoo cost $15 for adults and $11 for children.
The equation representing the budget for the trip is 15x + 11y = 1500.
where, x is the no. of adults and y is the number of children that are travelling.
If x = 20 and y = 120 then,
15(20)+11(120)=300+1320=1620 which is out of the budget of the school.
If 120 students want to go to school then, no. of adults that can travel can be determined as
15 x + 11 (120 )<= 1500
15x <=1500-1320
15x<=180
x <=12
Therefore, we can conclude that 120 students and 20 adults cannot travel for the trip but 120 students can travel with a maximum of 12 adults among with them as it will cost school the trip in the budget.

Answer:
Step-by-step explanation:
Given data
breadth=9 in
Length=11 in
Now a square of side x is cutted for each corner such that the cardboard is made into a open-top box with
length=11-2x
breadth=9-2x
height=x
Here substract 2x because from both sides of length and breadth x units are reduced.
therefore volume of new open-top box is
Volume(v)=
If the perimeter is 26 and the length of one side of the rectangle is 5cm longer than its breadth,
26 - 5 - 5 = 16
16 / 4 = 4 ( rectangle has 4 sides. )
the breadth is 4cm.
so the length must be 4+5=9cm.
