The Sampsons are starting to save money but still have not made any decision

about investing their money in CDs$.$ They are now concerned about potential

repair expenses for Sharon's car. They would like to have sufficient liquidity so

that if they need to buy her a new car immediately, they could afford a down

payment without being forced to cash in CDs early $($because they would be

charged a$.$penalty$).$ How might they revise their CD investing strategy to increase

their liquidity?
