Expert Answer

Step 1)

Elasticity of demand is given by,

E = -\\frac{p}{q}\\cdot \\frac{dq}{dp}

we have q = 39,000 - 3p2 hence,

E = -\\frac{p}{39,000-3p^2}\\cdot \\frac{d}{dp}(39,000-3p^2)

E = -\\frac{p}{39,000-3p^2}\\cdot (0-6p)

E = -\\frac{p}{39,000-3p^2}\\cdot (-6p)

E = \\frac{6p^2}{39,000-3p^2}

Step 2)

we know that total revenue ia maximized when E = 1

we have,

E = \\frac{6p^2}{39,000-3p^2}

Hence we can write,

\\frac{6p^2}{39,000-3p^2}=1

6p^2=39,000-3p^2

9p^2=39,000

p^2=\\frac{13,000}{3}

p=\\pm \\sqrt{\\frac{13,000}{3}}

price cannot be negative hence we have,

p= \\sqrt{\\frac{13,000}{3}}

we have,

q = 39,000 -3p^2

Hence we can write values of q at which revenue is maximum is given by,

q = 39,000 -3\\left ( \\sqrt{\\frac{13,000}{3}} \\right )^2

q = 39000 -3\\left ( \\frac{13,000}{3} \\right )

q = 39,000 -13,000

q = 26,000
