Tina buys 3 12 - packs of soda, for 3 * 12 = 36 sodas. 6 people attend the party, so half of them is 6 / 2 = 3 people. Each of those people drinks 3 sodas, so they drink 3 * 3 = 9 sodas. Two people drink 4 sodas, which means they drink 2 * 4 = 8 sodas. With one person drinking 5, that brings the total drank to 5 + 9 + 8 = 22 sodas. As Tina started off with 36 sodas, that means there are 36 - 22 = 14 sodas left. So the answer is 14.
