Heather Alburty purchased a previously owned, 2004 Grand Am for $8900.Since purchasing the car, she has spent the following amounts on parts and labor:

New stereo system$1,200

Trick paint400

New wide racing tires800

Total$2,400

Unfortunately, her new stereo doesn't completely drown out the sounds of a grinding transmission.Apparently, the Grand Am needs a considerable amount of work to make it reliable transportation.Heather estimates that the needed repairs include the following:

Transmission overhaul$2,000

Water pump400

Master cylinder work1,100

Total$3,500

In a visit to a used car dealer, Heather has found a 2005 Neon in mint condition for $9,400.Heather has advertised and found that she can sell the Grand Am for only $6,400.If she buys the Neon, she will pay cash, but she would need to sell the Grand Am.

Conceptual Connection:In trying to decide whether to restore the Grand Am or to buy the Neon, Heather is distressed because she already has spent $11,300 on the Grand Am.The investment seems too much to give up.How would you react to her concern?Assuming that Heather would be equally happy with the Grand Am or the Neon, should she buy the Neon, or should she restore the Grand Am?
