If you do not own a pediatric scale, you can calculate your child's weight by holding your baby and standing on a bathroom scale. Jot this number down; then stand on the scale without the child. Subtract the first number from this number, and you'll have your baby's weight. You can now use this number in the growth calculator to calculate your child's weight percentile.

Using the process, solve the problem below.
