    if my memory serves me write we write a 1 row 3 column matrix for the prices (3 5 7) - the price of the hammers , flashlights, lanterns pre-multiplying the product matrix by this price matrix gives the money taken in by each store for each product

    multiplying the other 2 columns gives a 3*3 matrix of all the money taken in by the 3 stores the sum of the amounts in the middle column gives you total revenue for all flashlights
