Dorothy and John Huffschneider listed their house and lot for sale with C. B. Property. The asking price was $165,000, and the owners told C. B. that the size of the property was 6.8 acres. Dean Olson, a salesman for C. B., advertised the property in local newspapers as consisting of six acres. James and Jean Holcomb signed a contract to purchase the property through Olson after first inspecting the property with Olson and being assured by Olson that the property was at least 6.6 acres. The Holcombs never asked for or received a copy of the survey. In actuality, the lot was only 4.6 acres. The Holcombs now seek to rescind the contract. Decision?
