Consider the following demand equation 11) x: +30 ( 4 9 Let x : g), with price p. Find ip) rm = Find the elasticity of demand, E(p]. EED) : Compute the elasticity of demand and determine whether the demand is elastic, unitary, or inelastic at the price p : 7. EU) : Elasticity of Demand for Hair Dryers The demand equation for the Roland portable hair dryer is given as follows where X (measured in units of a hundred) is the quantity demanded per week and p is the unit price in dollars. x: $225 7 oz) (0 5 pg 15) (a) Is the demand elastic or inelastic when p : E? O elastic O inelastic Is the demand elastic or inelastic when p : 11? O elastic O inelastic (b) When is the demand unitary? [Round your answer to two decimal places.) (Hint: Solve Efp) = 1 for p.) (c) If the unit price is lowered slightly from $11, will the revenue increase or decrease? 0 increase 0 decrease (d) If the unit price is increased slightly from $6, will the revenue increase or decrease? 0 increase 0 decrease
