The demand function for an item is given by d(x) = 100/ 0.01x 2 + 1 (20 ≤ x ≤ 50) where d(x) (measured in units of a thousand) is the quantity demanded per weak and x is the unit price in dollars.  (a) Find the rate of change in demand with respect to price. (b) How fast is the demand changing at price equal to 30 (x = 30)?

If consumers completely ceases purchasing a product when its price increases by any amount, the demand is :

The demand function for specialty steel products is given, where p is in dollars and q is the number of units. p = 135V110 - g (a) Find the elasticity of demand as a function of the quantity demanded, q. (b) Find the point at which the demand is of unitary elasticity. q = Find intervals in which the demand is inelastic and in which it is elastic. (Enter your answers using interval notation.) inelastic elastic (c) Use information about elasticity in part (b) to decide where the revenue is increasing, and where it is decreasing. (Enter your answers using interval notation.) increasing decreasing Use information about elasticity in part (b) to decide where the revenue is maximized. q =
