Question $5$

Hannah Rollins recently purchased a new car. While she originally desired to trade in her old car at the dealership where she bought her new car, a serious engine problem was detected when the car was being appraised, so the price the dealership offered Was quite low. Hannah decided that she could get a higher price if she sold it on her own, so she placed an ad in the paper. When a buyer from out$-$of$-$state came to look at her car, Hannah decided not to mention the engine problem.
