Answer:
$17.85
Step-by-step explanation:
Let the dollar amount per shirt be represented by s.
Let the dollar amount per pants be represented by p.
You have the following system:
3s+2p=104.81
2s+1p=61.33
If I multiply the bottom equation by -2, I can set the system up for elimination since the equations are already and the same form and I will have 2p and -2p in the same column there.  2p+(-2p)=0
Multiplying equation 2 by -2:
3s+2p=104.81
-4s-2p=-122.66
-----------------------Add the equations:
-1s      =-17.85
Multiply both sides by -1:
s=17.85
So one shirt cost $17.85

Answer:
Step-by-step explanation:
An odd function is symmetrical about the origin:
   f(-x) = -f(x)
So, ...
   f(-2) = -f(2) = -2
   f(-3) = -f(3) = -1
   f(-4) = -f(4) = -2
   f(-6) = -f(6) = -3
