You want to buy birthday hats, cards, and teddy bears for your best friends birthday party. You buy the products for wholesale prices, from the local party store. The hats cost $2.50, cards cost $0.90, and the teddy bears cost $3.10. You want to decorate each item for the party and the decorations for the hats cost $1.50, the decorations for the cards cost $0.60, and the decorations for the teddy bears cost $1.70.

In your own words, explain how you would construct a matrix to contain this data. Make sure you include the size and shape of the matrix and your logic for your construction methods.

I will create a five by four matrix to indicate the costs of the products.  The matrix will have five vertical columns and four horizontal rolls.  The vertical columns will show the product categories and the total costs for all the products and decorations.  The horizontal rolls will show the product costs, the decoration costs, and the total costs for each product category.

The size and shape of the matrix will be 5 by 4 with squared boxes.

Step-by-step explanation:

Total costs               $4.00        $1.50       $4.80       $10.30
