Final answer:
Carla, at 75, is part of the silent generation, which is characterized by individuals born before the Baby Boomers, from the mid-1920s to the early-to-mid 1940s.
Step-by-step explanation:
Carla is a 75-year-old woman whose life experiences of the Great Depression and World War II have influenced her spending habits, leading her to spend sparingly and buy only what is practical. Given that Carla is 75, she is most likely to belong to the silent generation, which is the cohort born before the Baby Boomers, specifically from the mid-1920s to the early-to-mid 1940s. The Baby Boomers, on the other hand, were born between 1946 and 1964 and came of age during the 1960s and early 1970s. They are known for redefining what it means to be young, middle-aged, and old, with an emphasis on avoiding the signs of aging. Therefore, Carla's age would place her in the Silent Generation, not the Baby Boomers, Generation X, Millennials, or Generation Z.
