K For the demand function q=D(p) = 500 - p, find the following. a) The elasticity b) The elasticity at p = 108, stating whether the demand is elastic, inelastic or has unit elasticity c) The value(s) of p for which total revenue is a maximum (assume that p is in dollars) a) Find the equation for elasticity. E(p)= b) Find the elasticity at the given price, stating whether the demand is elastic, inelastic or has unit elasticity. E(108)= (Simplify your answer. Type an integer or a fraction.) Is the demand elastic, inelastic, or does it have unit elasticity? elastic inelastic O unit elasticity h 13 see s 23​
