5. The sales S of a journal is a function of the number of pages devoted to important stuffabout economics (E) and the number of pages devoted to everything else (U):1S(E,U) = 100U + 310E – u-u? – 2E? – UE-2a. What should be the number of pages devoted to economics articles and the number ofpages devoted to articles on other topics in order to maximize sales?b. Verify that your answer to part (a) satisfies the second order conditions for a maximum.
