Let x be Chad's and Sally's age (in years).
Hailey's age is x%2B4 because she "is 4 years older than chad".
Chad's mother's age is x%2B24 because "chad's mother was 24 when chad was born".
Chad's father's age is %28x%2B24%29%2B3=x%2B27 because "chads father is threee years older than his mother".
The average age of those 5 people is
%28x%2Bx%2B%28x%2B4%29%2B%28x%2B24%29%2B%28x%2B27%29%29%2F5=22
%285x%2B4%2B24%2B27%29%2F5=22
%285x%2B55%29%2F5=22
5x%2F5%2B55%2F5=22
x%2B11=22%7D%7D%0D%0A%7B%7B%7Bx=22-11
highlight%28x=11%29
Chad and his twin sister are highlight%2811%29.
Chad's sister Hailey is 11%2B4=highlight%2819%29.
Chad's mother is 11%2B24=highlight%2835%29.
Chad's father is 35%2B3=highlight%2838%29
