The demand for a new computer game can be modeled by p left parenthesis x right parenthesis equals 43.5 minus 9 ln xp(x)=43.5−9lnx where p(x) is the price consumers will pay, in dollars, and x is the number of games sold, in thousands. recall that total revenue is given by upper r left parenthesis x right parenthesis equals x times p left parenthesis x right parenthesisr(x)=x•p(x). complete parts (a) through (c) below. a) find r(x). r(x)-□ b) find the marginal revenue, r'(x) r'(x) c) is there any price at which revenue will be maximized? why or why not?
