Question

Alexis weighs 6.5 pounds at birth. Assuming her development proceeds normally, she should weigh about _____ pounds by her first birthday.

A. 13.0
B. 16.5
C. 19.5
D. 23.5

Answer 1

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.
