Formulate the situation in matrix form. Be sure to indicate the meaning of your rows and columns. Find the requested quantities using the appropriate matrix arithmetic. A car dealer sells sedans, station wagons, vans, and pickup trucks at sales lots in Oakdale and Roanoke. The "dealer markup" is the difference between the sticker price and the dealer invoice price. The dealer invoice prices at both locations are the same: $14,000 per sedan, $18,000 per wagon, $23,000 per van, and $27,000 per pickup. The sticker prices at the Oakdale lot are $16,900 per sedan, $22,900 per wagon, $25,900 per van, and $31,900 per pickup, while at the Roanoke lot the sticker prices are $18,900 per sedan, $21,900 per wagon, $26,900 per van, and $30,900 per pickup. Represent these prices as a dealer invoice matrix D and a sticker price matrix S. Use these matrices to find the dealer markup matrix M for these vehicles at these sales lots.
