Tina buys 3 12-packs of soda for a party.  Including Tina, 6 people are at the party.  Half of the people at the party have 3 sodas each, 2 of the people have 4 and 1 person has 5.  How many sodas are left over when the party is over?
Tina buys 3 12-packs of soda, for 3*12= <<3*12=36>>36 sodas
6 people attend the party, so half of them is 6/2= <<6/2=3>>3 people
Each of those people drinks 3 sodas, so they drink 3*3=<<3*3=9>>9 sodas
Two people drink 4 sodas, which means they drink 2*4=<<4*2=8>>8 sodas
With one person drinking 5, that brings the total drank to 5+9+8=<<5+9+8=22>>22 sodas
As Tina started off with 36 sodas, that means there are 36-22=<<36-22=14>>14 sodas left
