Chris bought 8 movies on DVD for $12 each, so he spent 8 * $12 = $96 on DVD movies.
He also bought 4 movies on Blu-ray for $18 each, so he spent 4 * $18 = $72 on Blu-ray movies.
In total, Chris spent $96 + $72 = $168 on all the movies.
Chris bought a total of 8 + 4 = 12 movies.
To find the average price per movie, we divide the total amount spent by the number of movies.
So, the average price per movie is $168 / 12 = $14.
#### 14
