4
Step-by-step explanation:
The completion of the table is shown below;
Price Quantity Demanded Quantity Supplied
($ per widget) (widgets) (widgets)
$2 5 1
$4 5 2
$8 5 3
$12 4 4
$20 3 5
$32 2 5
$44 1 5
As we can see that at the price of $12 the quantity demanded is equivalent to the quantity supplied i.e 4 so here the equilibrium quantity is 4 for the widgets
