Solve.Elissa sells two breeds of dogs, Alaskan Malamutes and Great Pyrenees. She has 114 feet of fencing to enclose two adjacent rectangular dog kennels, one for each breed. An existing fence is to form one side of the kennels, as in the drawing below. Let x represent the measurement indicated. Express the total area of the two kennels as a function of x. Graph the function and from the graph determine the value of x, rounded to the hundredths place, that will yield the maximum area.

Solve the problem.A bookstore is having a sale. All books included in the sale have a colored sticker on them to indicate the sale price. There are green stickers, red stickers, and orange stickers. Bob, Sue, and Fred each make purchases of books that are on sale. Each row of the table gives information about the numbers of book purchases and the total cost of the purchase (before taxes) . 
Use this information to set up a matrix equation of the form 
which can be solved to determine the price for each type of sale book. Solve this matrix equation to find the price of
a book with a green sticker.Use the fact that for A =
