Solve this problem

Solve the problem. A bakery sells four main items: rolls, bread, cake, and pie. The amount of each of five ingredients (in cups, except for eggs) required to make a dozen rolls, a loaf of bread, a cake, or a pie is given by matrix A. Eggs Flour Sugar Shortening Milk Rolls 2 2 Bread 3 4 0 0 = A Cake 3 2 2 1 1 Pies 2 2 W / H 0 Suppose a day's orders total 20 dozen rolls, 200 loaves of bread, 50 cakes, and 60 pies. Write the orders as a 1 x 4 matrix and, using matrix multiplication, find a matrix for the amount of each ingredient needed to fill the day's orders
