How would I solve these two problems? I believe I may have made a few miscalculations somewhere but cannot find out where I miscalculated the profit for LoS Angeles in the first problem and number of foreclosures in August in the second problem. (This has to do with matrix multiplication) thank you!

MY NOTES Profit In January, the Left Coast Bookstore chain sold 700 hardcover books, 1,800 softcover books, and 2,500 plastic books in San Francisco; it sold 400 hardcover, 500 softcover, and 500 plastic books in Los Angeles. Hardcover books sell for $30 each, softcover books sell for $10 each, and plastic books sell for $15 each. Suppose that each hardcover book costs the stores $10, each softcover book costs $5, and each plastic book costs $10. Use matrix operations to compute the total profit at each store in January.
