Answer:
C. 19.5
Explanation:
The simplified linear equation derived to calculate mean weight for Children aged 1-5 years: Weight (kg) = 2 x (age in years + 5.5)
Alexis weighs 6.5 pounds at birth
Assuming her development proceeds normally, after one year:
Weight = 2 x (1 + 5.5)
= 2 x ( 6.5)
= 13
∴ (13 + 6.5) pounds = 19.5 pounds.
