Final answer:
To find the total age of Jeremy, Quan, Karen, and Randy now, we calculate the time elapsed (6 years per person for 4 people) and add that to their total age from 6 years ago to get 44 years.
Step-by-step explanation:
The question is asking us to calculate the total age of Jeremy, Quan, Karen, and Randy as of today. Since their combined age was 20 years 6 years ago, we first need to acknowledge that each person has aged 6 years since that time. So, if there are 4 people, we calculate 6 years times 4 people to determine how much older they have all become collectively.
6 years/person × 4 people = 24 years
Next, we add this amount to the total age they were 6 years ago:
20 years + 24 years = 44 years
Therefore, the total age of Jeremy, Quan, Karen, and Randy now is 44 years.
