Final answer:
To earn the most possible interest on $500, Pam should consider utilizing a Certificate of Deposit (CD), which offers higher interest rates than regular savings accounts.
Step-by-step explanation:
To earn the most possible interest on her $500 investment, Pam should consider utilizing a Certificate of Deposit (CD). With a CD, she agrees to deposit a certain amount of money for a stated period of time, typically ranging from a few months to several years. In exchange, the bank offers a higher interest rate than a regular savings account.
CDs are a good option for long-term savings because they provide a fixed interest rate and are FDIC insured, meaning that the money is protected by the government up to a certain amount. However, there is a substantial penalty for early withdrawal.
