Question
Suppose you are given a budget of $V million and are tasked with maximising the number of pre-orders. It costs $1000 to rent a billboard
Suppose you are given a budget of $V million and are tasked with maximising the number of pre-orders. It costs $1000 to rent a billboard and $C million to sign a celebrity spokesperson. Finally, suppose
g(b,s) =b^1/2 +2500s^1/4
where b is the number of billboards rented and s is the number of celebrity spokespeople signed.
1. Write the constrained maximization problem
2. Can the inequality constraint hold with strict inequality? Justify your answer using a complementary slackness argument.
3. Relate your answer in part 2 to the interpretation of the Lagrange multipliers value
4. Find the equation relating the optimal number of celebrity spokes people to hie with V and C
5. Holding everything else fixed, how does the optimal number of spokespeople change in C ,eg. What is s(C)? Interpret its sign
