13.7
i honestly don't know how to get this answer but when i turned in my test i got this question right by guessing 13.7
To answer the question above, we let s be the cost of a shirt and h be the cost of each hat such that the equations that would best represent the given are:
10s + 20h = 490
20s + 30h = 860
The system of equations is the answer to the first question and the values of s and h are $25 and $12, respectively.

Basically, inverse Property of Addition states that if you add any number added to its opposite the result will be equal zero. So, here we have the following equation:
![x + 12 = 47](https://tex.z-dn.net/?f=x%20%2B%2012%20%3D%2047)
Adding -12 to both sides we get:
![x + 12 - 12= 47-12 \\ \\ \\ But \ 12+(-12)=0 \\ \\ \\ So: \\ \\ x + 0= 35 \\ \\ Finally: \\ \\ \boxed{x=35}](https://tex.z-dn.net/?f=x%20%2B%2012%20-%2012%3D%2047-12%20%5C%5C%20%5C%5C%20%5C%5C%20But%20%5C%2012%2B%28-12%29%3D0%20%5C%5C%20%5C%5C%20%5C%5C%20So%3A%20%5C%5C%20%5C%5C%20x%20%2B%200%3D%2035%20%5C%5C%20%5C%5C%20Finally%3A%20%5C%5C%20%5C%5C%20%5Cboxed%7Bx%3D35%7D)
