If Billy sleeps 6 hours one night, then 2 more hours than that the following night, and then half the previous amount the following night, and then finally triple the previous amount the final night, how much did he sleep in that four day period?

Billy slept 6 hours the first night. He then slept 6+2=<<6+2=8>>8 hours the second night.
Billy then slept 8/2=<<8/2=4>>4 hours the third night.
Finally, Billy slept 4*3=<<4*3=12>>12 hours the fourth night.
In total, Billy slept 6+8+4+12=<<6+8+4+12=30>>30 hours.
#### 30
