A department store has 700 pairs of purple Capri stretch pants that it must sell in the next four weeks. The store manager knows that demand by week for the next four weeks will be linear each week, with the following price-response functions:
Week 1: d1(p1) =1,000 -100p1 Week 2: d2(p2) =800 -100p2 Week 3: d3(p3) = 700 - 100p3 Week 4: d4(p4) =600 -100 p4
Assume that the demands in the different weeks are independent, that is, that customers who do not buy in a given week do not come back in subsequent weeks. Assume she can charge a different price each week. What are the optimum prices by week she should charge? What is her corresponding revenue?
Week 1: d1(p1) = 1000 -100*p1
Week 2: d2(p2) = 800 -100*p2
Week 3: d3(p3) = 700 - 100*p3
Week 4: d4(p4) = 600 -100*p4
This can be formulated as an optimization problem as below:
Max d1*p1+d2*p2+d3*p3+d4*p4 or,
Max (1000-100p1)p1+(800-100p2)p2+(700-100p3)p3+(600-100p4)p4 or,
Max 1000p1+800p2+700p3+600p4-100(p1^2+p2^2+p3^3+p4^2)
s.t.
d1+d2+d3+d4 <= 700
p1, p2, p3, p4 >= 0
Optimal solution is determined by Excel Solver as follows:

Hi there! I need to compare two essay into 1 essay, and make it interesting and choose couple topics which im going to talk about in my essay FIRST ESSAY “Teaching New Worlds/New Words” bell hooks Like desire, language disrupts, refuses to be contained within boundaries. It speaks itself against our will, in words and thoughts that intrude, even violate the most private spaces of mind and body. It was in my first year of college that I read Adrienne...
