The table shows the Hornet nation’s demand for stingers. The marginal cost of stingers for each seller is $10. If there are six sellers of stingers in Hornet and if they collude, then what will be the price and quantity of each seller?

In order to maximize profit a firm produces that quantity at which MR = MC
where MC = marginal cost and MR = Marginal revenue.
Here six firms collude and hence will work together and produce that quantity at which MR = MC
Here, MC = 10
MR = Change in TR / Change in Q
where TR is total revenue from Q units, Marginal revenue is the marginal revenue from Qth unit and Q = quantity.
We can see from above that when Q = 30 then MR = Change in TR / Change in Q = (420 - 320)/(30 - 20) = 10
Hence MR = MC when Q = quantity = 30 units.
We can see from above table that When Q = 30 then consumers are willing to pay $14 and hence they will charge $14.
Assuming each firm will have equal market share thus quantity produced by each firm = Total quantity/ number of firms = 30/6 = 5.
Hence each firm will produce quantity = 5 units and will charge Price = $14
