Textbook Problem

Advertising and sales Suppose that a company’s sales volume y (in thousands of units) is related to its advertising expenditures x (in thousands of dollars) according to

x y 20 x + 10 y = 0

Find the rate of change of sales volume with respect to advertising expenditures when x = 10 (thousand dollars).

To determine

To calculate: The rate of change of sales volume with respect to advertising expenditures when x=10 if sales volume y is related to its advertising expenditures x according to the equation, xy20x+10y=0.

Explanation

Given Information:

Sales volume y (in thousands of units) is related to its advertising expenditures x (I thousands of dollars) according to the equation, xy20x+10y=0.

Formula used:

According to the product rule of derivatives,

ddx(uv)=udvdx+vdudx

Calculation:

The sales volume y is related to its advertising expenditures x according to the equation,

xy20x+10y=0

Now, the rate of change of sales volume with respect to advertising expenditures is given by dydx.

Now, differentiate both sides with respect to x as,

ddx(xy20x+10y)=ddx(0)

Now, use the product rule of derivatives,

ddx(uv)=udvdx+vdudx

To obtain the derivative of xy as,

ddx(xy)20dxdx+10dydx=0xdy
