Solution Summary: The author explains the expression of R(x) by when the demand for a new computer game can be modeled.
The expression of R(x) by when the demand for a new computer game can be modeled by p(x)=53.5−8lnx. Here, p(x) is the price that consumer pay in dollar and x is the number of games sold in thousand. The expression of total revenue is calculated by R(x)=xp(x).

To determine
To calculate: The marginal revenue, R′(x) of the function R(x)=xp(x). When the demand for a new computer game can be modeled by p(x)=53.5−8lnx.
(c)
To determine
To calculate: The price at which revenue will be maximum of the function p(x), when the demand for a new computer game can be modeled by p(x)=53.5−8lnx. The expression of total revenue is calculated by R(x)=xp(x).

It is bounded by y = x¹/3, y = 1, and x = 0.
We want to evaluate this double integral.
ONLY ONE order of integration will work.
Good luck!
