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

Hailey, Megan, and Bailey have saved $458 for a summer trip to the beach. Hailey has saved $167. Megan has saved at least $152,

Jet001 [13]

Let H = Hailey, M = Megan, B = Bailey

H + M + B = 458
167 + M + B = 458
M + B = 291

152 ≤ M ≤ 164
If M = 152, B = 139
If M = 164, B = 127

Thus,
$127 ≤ B ≤ 139
