Appleton Appliances is planning a big refrigerator sale. The first 100 customers who buy refrigerates will receive kitchen step stools free. The store has 200 stools in stock. One hundred stools were purchased several months ago for $20 per stool. The other 100 stools were just recently received and cost the store $25 per stool. The stools are identical. Mr. Appleton has decided to give away the strols that cost $20 because, he says, "As long as I'm giving them away, I might as well give away the ones with a lower cost." Do you agree with his rationale? Explain.
