Answer: 55 people attend aerobics at Martha’s altogether
Step-by-step explanation:
Martha conducts aerobics three times a week in her home.
Number of members in first group = 19 members
Number of members in second group = 22 members ; and
Number of members in third group = 14 members
To find the number of people who attended aerobics we have to add the number of members in all tge three groups.
So, number of people who attended aerobics at Martha’s altogether = 19 + 22 + 14 = 55 members
Hope it helps.
Thank you :)
