Answer:
Candy is 21 years old
Step-by-step explanation:
If Alisa is 16 years old, that would mean that Barbara would be 8, since she is half of Alisa's age.
If we add 5 to Alisa's age, we get 21. To find the average of their ages, we add them all up, and divide by how many people there are (3).
16+8+21=45
45÷3=15
