Answer:
The point equilibrium is obtained as the '30 graphic T-shirts are on sale for $ 10'.
Explanation:
From the graph, the cost price and selling price both of 30 graphic T-shirts are equal to $ 10 as the supply and demand price curves intersect at (30, $10).
Hence the point equilibrium is obtained as the '30 graphic T-shirts are on sale for $ 10'.
We know that the point of equilibrium, i. e., Cost price = Selling price is obtained where the supply and demand price curves intersect.
