I hope there is a typo and the problem should read that after 6 months the baby weighs 17 pounds and is 25 inches tall, because 66 months is 5 and a half years old, and a five year old child of that size would be dead or about to die from malnutrition or starvation.

If a child is born weighing 11 pounds and measuring 22 inches in length,
and 6 months later weighs 17 pounds and measures 25 inches in length,
assuming that weight, , and length, ,
are linear functions of time , in months,
those functions are
<---> and
<---> .
Then, assuming that the child continues to grow linearly,
at 1 year old , the child's weight and height would be
<---> and
<---> .
