  5. A furniture store marks up its “list” prices by 62.5% over cost, but then marks the list prices down by 20%. What is the

F. Additional Exercises



  1. Automobiles are usually listed for sale at a price suggested by the manufacturer (the manufacturer’s suggested retail
    price (MSRP)), also called the sticker price. The invoice price is the cost of the vehicle listed on the invoice (i.e., the
    bill) sent to the manufacturer. While most people think of the invoice price as the dealer’s cost, in reality most car
    manufacturers lower the price to the dealer by a holdback, a further discount below the invoice price.


Suppose that a new car has a $29,995 list price, and a $26,792 invoice price. The holdback is 3% of the invoice
price.


a. Calculate the dealer’s actual cost for this car.
b. Suppose that a car dealer offers to sell this car for “1% over invoice.” Calculate the amount of markup over invoice
and the price at which the dealer is offering the car for sale.
