Indicate the pointcorresponding to the situation when the supply S equals the demand D (that is,the market is in equilibrium) and determine the number of articles produced inthis case. Find also the selling price corresponding to the equilibrium state of themarket.(b) When the government levies a tax of £10 per item sold, the customers areconcerned only with the new total retail price £P, whereas the suppliers react asthough the price was £(P – 10).
