Students in Mr. Sparks' class spent an average of 3.2 hours last night Facebook messaging about who had a crush on who. The same amount of students spent another 2.8 hours last night texting about how dumb school is, how dumb their parents are, and who is dating who. If Mr. Sparks' students only had 6.5 hours free last night before they passed out due to sheer exhaustion from their social life, how many hours were left to study for tomorrow's Chapter 3 test?
0.5 hours. Students, please take longer than a half hour to study tonight. School will still be dumb, your parents will still be dumb, and you will not miss out on who broke up with who. Middle school relationships usually last 2.5 days anyway. Please study. You guys will do very awesome tomorrow!!!
