Answer:
The answer is actually 13.2, don't listen to the guy on top of my post.
Step-by-step explanation:
The other limp-brain moron on top of me didn't know math and said it was just 13, but it's actually 13.2
( FOH him ) Last time I checked on the test, there wasn't a "13" option so god knows what type of Mickey Mouse math this idiot knew, So the answer is 13.2
