Matrix Competition Group 3

A new pasar malam was set up along the street. There were three shops, A, B and C, selling handbags. Shop A sells 35 Addidas handbags 20 Converse handbangs and 30 Nike handbags. Shop B sells 20 Addidas handbags, 25 Converse handbags and 40 Nike handbags. Shop C sells 40 Addidas handbags, 30 Converse handbags and 15 Nike handbags. Each Addidas handbag cost $20, each Converse handbag cost $10 and each Nike handbag cost $25. For every handbag sold, the shop gives a discount.

Write down three matrices such that the elements of their product, under matrix multiplication will give the total cost of the handbags sold by the three shops.
