Chapter 2.6, Problem 5E

(a)

To determine

The value of the current daily revenue, where the daily revenue, in dollars, from the sale of $x$ lawn chairs is $R\left(x\right)=0.005x^3+0.01x^2+0.5x$ and $70$ lawn chairs are sold daily.

(b)

To determine

To calculate: The increase in revenue when $73$ lawn chairs were sold each day. Where the daily revenue, in dollars, from the sale of $x$ lawn chairs is $R\left(x\right)=0.005x^3+0.01x^2+0.5x$

(c)

To determine

To calculate: The estimate the marginal revenue, if $70$ lawn chairs are sold daily where the daily revenue, in dollars, from the sale of $x$ lawn chairs where $R\left(x\right)=0.005x^3+0.01x^2+0.5x$.

(d)

To determine

To calculate: Estimate the value $R\left(71\right)$, $R\left(72\right)$ and $R\left(73\right)$ from part (c). Where, the daily revenue, in dollars, from the sale of $x$ lawn chairs is $R\left(x\right)=0.005x^3+0.01x^2+0.5x$
