For 1 - 12y < 3y+1;        y > 15
For 2 - 6y  >  4  +  4y;   y  <  -0.2
The given inequalities are:
1  -  12y < 3y  +  1
2 - 6y  >  4  +  4y
For 1  -  12y < 3y  +  1:
1  -  12y < 3y  +  1
Collect like terms
-12y  -  3y  <  1  -  1
-15y    <   0
Multiply both sides by -1
-1(-15y)   >  0(-y)
15y    >   0
Divide both sides by 15
y   >  0/15
y   >   15
For 2 - 6y  >  4  +  4y
Collect like terms
-6y  - 4y  >  4  -  2
-10y   >   2
Multiply both sides by -1
-1(-10y)   <  2(-1)
10y   <  -2
y  <  -2/10
y  <  -0.2

I think it’s 12, if you take $360 and subtract the $120 deposit you get 240 and i divided that by 20 to get 12.
        
             
        
        
        
Yeah, dude it sure is. 
I'm assuming you wanted something like this?
40x + 4.5y = 112
x = Days
y = Pairs of shoes
112 = Total profits 
 
        
             
        
        
        
You can do this by finding the lengths of RT , RS and ST using the distance formula
RT = sqrt ((0- -5)^2  + (4 - -6)^2)
      = sqrt (5^2 + 10^2)  = sqrt 125
RS =  sqrt ((-3- -5)^2 +  (-2 - -6)^2))
       = sqrt  ( 2^2 + 4^2)  = sqrt 20
ST  = sqrt 125 - sqrt 20
RS / ST  = sqrt 20 / (sqrt 125-sqrt 20)
so the ratio RS:ST = 2:3
Its B
