Step-by-step explanation:sdfdsfds
It should be $4 sorry if it is wrongbut i pretty sure that is he answer
Answer:
4x + 8y = 20
-4x + 4y = -10
12y = 10
y =10/12= 5/6
4x + 8(5/6) = 20
4x + 40/6 = 120/6
4x = 80/6
x = 3 1/3 or 10/3
4(10/3) + 8y = 20
40/3 + 8y = 60/3
8y = 20/3
y = 5/6
Step-by-step explanation:
It would be 15 because the 35 people at most minus the 20 students equals 15 so that would be the greatest number of adults allowed to be there.
