The following equations describe monthly demand and supply relations of a firm
Qd = 500 – 5 P
Qs = - 100 + 2 P
1- At what price level would demand equal zero?
2- At what price level would supply equal zero?
3- Determine the market clearing price and output level and graphically show it.
4- Find elasticity of demand and comment whether it is elastic or inelastic.
5- Find elasticity of supply and comment whether it is elastic or inelastic.
6- If firm want to increase its sale by 100,000, what price will it charge?
7- If firm increases its price by AED 1, what will be the equilibrium output?
