Solve the problem. 1) Three different clothing stores order the following amounts of clothing by a certain designer Jackets Shirts Suits Store 1: 40 50 10 Store 2: Store 3: 10 30 10 40 30 40 The unit prices of each product are given below for two suppliers: Supplier A Jacket 85 Shirt Suit 30 180 Supplier B 90 30 200 a) What matrix product displays the cost to each store of buying the clothes from each supplier? (20 points) b) Display the two matrices which must be multiplied and their product (20points) 2) Barnes and Able sell life, health, and auto insurance. Sales for May and June are given in the matrices. Life Health M- 20,000 15,000 7000 Able 30.000 17,000 Ba Life Health Auto 1- 70000 10,000 Able 20,000 21.000 12.000 Banes Find the matrix that would give total sales for the months of May and Junc (30 points) 3) Solve the system of equations. If the system is dependent, express solutions in terms of the parameter z. (Consider using Cramer's rule of 3x3 matrices in solving this question) 5)x+y+z--1 x-y+3z-7 3x+y+z-3 (30 points)
