Hybrid and electric cars have gained in popularity in the last decade as a consequence of high gas prices. But their great gas mileages often come with higher car prices. There may be savings, but how much and how long before those savings are realized? Suppose you are considering buying a Honda Accord Hybrid, which starts around $31,665 and gets 48 mpg. A similarly equipped Honda Accord will run closer to $26,100 but will get 31 mpg. How long would it take for the Prius to recoup the price difference with its lower fuel costs,assuming you drive 800 miles per month?

Delta Properties builds houses. They have two models, Economy and Deluxe. The cost to build depends on the square footage of the house and the size of the lot. Of course, the house and lot for the Deluxe model are larger than those for the Economy model. The size of the house and the lot size for each model is given in the table below, in number of square feet: Economy Model Deluxe Model Size of Building Size of Lot 2200 5000 3300 8000 The next table gives Delta's cost per square foot to build a house and to buy a lot, in dollars. Building Cost Lot Cost 500 100 The size and cost information is summarized in the following matrices: S 2200 5000 L3300 8000 C= 500 100 a. Compute the product SC. Preview b.
