Option: B is the correct answer.
The number of board games that the sellers are willing and able to sell at $20 is:
B) 200
By looking at the graph we observe that the points that are plotted in the graph are as follows:
Quantity supplied Price ($)
100 10
200 20
300 30
400 40
500 50
Hence, we see that when the selling price of the items was $ 20
then the number of board games that were sold were: 200
