The supply curve for steel is 90x−y=−50. The demand curve is 10x+y=200. x is quantity in thousands of metric tons y is price in

ivolga24 [154]

Answer:

The intersection point of the two curves is $(x,y) = \left(\frac{3}{2}\,kton.m, 185\,USD \right)$ .

Step-by-step explanation:

From statement we get the following equations:

Supply curve

$90\cdot x - y = -50$ (1)

Demand curve

$10\cdot x + y = 200$ (2)

Where:

$x$ - Quantity, measured in thousands of metric tons.

$y$ - Price, measured in US dollars per metric tons.

If we add both equations, then we find that quantity is:

$(90\cdot x -y )+(10\cdot x +y) = -50+200$

$100\cdot x = 150$

$x = \frac{3}{2}\,kton.m$

Then, we finally find the price by substituting on (2):

$y = 200-10\cdot \left(\frac{3}{2} \right)$

$y = 200-15$

$y = 185\,USD$

The intersection point of the two curves is $(x,y) = \left(\frac{3}{2}\,kton.m, 185\,USD \right)$ .
