sally is chads twin sister::::::::::::::::::::::::::::s = c
chads sister hailey is 4 years older than chad::::::::h = c+4
chads mother was 24 when chad was born::::::::::::::::m = c+24
chad father is 3 years older than his mother::::::::::f = c+27

2. The average age of the 5 family members is 22. determine the age of chads sister hailey.
Equation:
(c + c + c+4 + c+24 + c+27)/5 = (5c + 55)/5 = c + 11
c+11 = 22
c = 11 yrs old (chad's age)
hailey = c+4 = 15 yrs old
