8th grade = 3x = 3(47) = 141 band members.

7th + 8th = 188

7th = x
8th = 3x

x + 3x = 188    ; x = 47 ;  47 + 3(47) = 47 + 141 = 188
4x = 188
4x / 4 = 188 / 4
x = 47 --> 7th grade

8th grade = 3x = 3(47) = 141

To check:
x + 3x = 188    ; x = 47 ;
47 + 3(47) = 188
47 + 141 = 188
188 = 188

Let the size of the seventh grade band be s
That means the size of the eighth grade band must be 3s because it is 3 times as big as the seventh grade band.
Combined, the two bands have 188 members.
3s and s combined is 4s. Thus 4s must equal 188.

4s = 188
s= 47
3s = 141

The eighth grade band has 141 members.

A warden meets with 23 prisoners. He tells them the following:
Sedbober [7]
The prisoners could do a pattern that could signal who has already been in the room. So for example, one light off, both lights off, one light on, both lights off. But with left and right lights to make the sequence last as long as possible. Then after that sequence to have the last one be the signal that everyone has been in there. I dunno this is tricky lol
