Step 1
10x^2. The derivative of this function is y' = 6 - 0.20x. To find the maximum point, we set the derivative equal to zero and solve for x: 6 - 0.20x = 0 0.20x = 6 x = 6 / 0.20 x = 30 So, the level of marketing expenditure that will maximize sales is $30. Show more…

A company estimates that it will sell $N(x)$ units of a product after spending $x$ dllar thousand on advertising, as given by $$ N(x)=-0.25 x^{4}+13 x^{3}-180 x^{2}+10,000 \quad 15 \leq x \leq 24 $$ When is the rate of change of sales increasing and when is it decreasing? What is the point of diminishing returns and the maximum rate of change of sales? Graph $N$ and $N^{\prime}$ on the same coordinate system.
