Final answer:
Lynn will be able to purchase alcohol on her 21st birthday, which falls on November 30, 2020, as the legal drinking age is 21 in most parts of the United States.
Step-by-step explanation:
Lynn was born on November 30, 1999. To determine when Lynn will be able to purchase alcohol, we need to calculate when she will reach the legal drinking age, which in most jurisdictions in the United States is 21 years old. By adding 21 years to her birth year (1999), we get 2020 as the year when Lynn turns 21. However, we need to consider the exact date. Since Lynn's birthday is on November 30, she will turn 21 exactly on November 30, 2020. Therefore, the correct answer is:
a. November 30, 2020
Lynn's Age to Purchase Alcohol
