For the demand function q=D(p)=200/(2+p) find the followingA. Elasticity B. The elasticity at p=4 stating wether the demand is elastic, inelastic, or has unit elasticity C. The values of p for which total revenue is a maximum

For the demand function q = D(p) = 200 find the following. (p+ 2)4 a) The elasticity b) The elasticity at p = 4, 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(4) = (Simplify your answer. Type an integer or a fraction.) Is the demand elastic, inelastic, or floes it have unit elasticity? A. unit elasticity O B. elastic O C. inelastic c) The value(s) of for which total revenue is a maximum (assume that is in dollars). (Round to the nearest cent as needed. Use a comma to separate answers as needed.)
