Selma agreed to buy a used car from Hillary for $2,000. Hillary drew up the contract
providing that the exchange would occur the next week. Unfortunately, Hillary was not very good
with the keyboard and typed in $1,200 as the price of the car. Selma noticed that the contract
said $1,200, not $2,000, and was very pleased. She signed it without saying anything. When it
was time to make the exchange, Selma gave Hillary $1,200. In response to Hillary’s inquiry
regarding an additional $800, Selma pulled out the contract and showed her that it said $1,200.
Hillary immediately responded that she had made a typographical error. Selma said that there
was no mistake on her part because she knew exactly what she was doing and that she thought
that Hillary had decided to give her a deal on the car. Which of the following is Hillary’s best
argument for a rescission of the contract?
