At the equilibrium price p, we can solve for the quantity of goods x :
demand = supply
5200 - 0.0005x = 2800 + 0.0003x
2400 = 0.0008x
x = 3,000,000
With this quantity of goods, the equilibrium price is
p = 5200 - 0.0005 (3,000,000)
p = 5200 - 1500
p = 3700
 
        
             
        
        
        
if you look at the part where the first part connects with the second part:
y = 5 if x < - 2
y = -2x + 1 if  -2 ≤ x < 1
we don't have a discontinuity there, so there shouldn't be a dot.

What is wrong with the graph?</h3>
When we graph over intervals like (a, b) or [a, b] or something like that, we use dots to define the end of the intervals, and to denote that the function ends abruptly or we have a jump.
In this case, you can see that between the end and the second part and the beginning of the third part there is a jump, so the use of dots is correct there, but if you look at the part where the first part connects with the second part:
y = 5 if x < - 2
y = -2x + 1 if  -2 ≤ x < 1
we don't have a discontinuity there, so there shouldn't be a dot.
That is the only error with the graph.

Answer:
(1, 3)
Step-by-step explanation:
  2x + 3y =  11      ------------(i)
-4x + 2y = 2        ------------(ii)
Multiply equation (i) by 2.
(i)*2              4x + 6y = 22
(ii)               <u>-4x  + 2y = 2</u>                  {Now add and x will be eliminated}
                             8y = 24
y= 24/8
y = 3
Plugin the value of y in equation (i)
2x + 3*3 = 11
2x + 9 = 11
2x = 11-9
2x = 2
x = 2/2
x = 1
 
        
             
        
        
        
Well it would be 63$ if we are not including tax because 80-17=63
