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:$17,000per sedan,$21,000per wagon,$24,000per van, and$27,000per pickup. The sticker prices at the Oakdale lot are$20,900per sedan,$25,900per wagon,$27,900per van, and$31,900per pickup, while at the Roanoke lot the sticker prices are$21,900per sedan,$24,900per wagon,$28,900per van, and$30,900per pickup. Represent these prices as a dealer invoice matrixDand a sticker price matrixS. Use these matrices to find the dealer markup matrixMfor these vehicles at these sales lots. (Let row 1 represent the dealer in Oakdale and row 2 represent the dealer in Roanoke.)
