for the following demand function, find a. E and b. the values of q (if any) at which total revenue is maxmized.

q= 36400-9p^2

a determine the elasticity of demand E

E= (type an expression using p as the variable.)

b determine the value of q that maxmimzes the reveune.

total reveune is maxmized at about q=

(round the nearest whole number as needed.)
