I'm completely lost with this question. I'mnot exactly sure how to go about doing matrix inversion
any help is greatly appreciated
A distributor has given three customers a deal on three products. He sold 10 units of product A, 5 units of product B, and 12 units of product C to the first customer for $66. He sold 5, 7, and 10 units of A, B, and C, respectively to the second customer for $54. Finally, the third customer
received 6 units of each product for $42. Government regulations require that the distributor make individual product prices known and that the prices be the same for all customers. Set up the problem, put it in matrix format, and solve, using matrix inversion, for the implicit prices he charged to his customers.
