  Solution
q = 40,200 - 8p2
a. Elasticity of demand, E = (dq/dp)*(P/q)
From the demand equation we get, (dq/dp) = d(40,200 - 8p2)/dp = - 16 p
Therefore, E = -16p (p/q) = -16p2/q = -16p2/(40,200 - 8p2)
Answer: E = -16p2 / (40,200 - 8p2)
B) Total revenue is maximized when value of elasticity is (-1) or, when absolute value of elasticity is 1 i.e. Total revenue is maximized when the demand is unitary elastic.
Therefore,
- 1 = - [16p2/(40,200 - 8p2)]
Or, 16p2 = 40200 - 8p2
Or, 24p2 = 40200
Or, p2 = 1675
From the demand equation we get, when p2= 1675,
q = 40200 - (8*1675) = 26800
Therefore, total revenue is maximized at q = 26800
