Question

A baby weighed 8 pounds when she was first born. She weighed 15 pounds at her 6-month doctor's check-up. What was her percent increase in weight from birth to 6 months? O A. 87.5% OB. 90% O C. 53% D. 7%

Answer 1

Given:

Initial weight is 8 pounds.

Final weight after 6 months is 15 pounds.

The objective is to find the increase in weight from birth to 6 months.

The increase in percentage of initial weight can be calculated as,

`((x)/(100))Initial\text{ weight=Final weight}`

Substitute the given values in the above equation.

`\begin{gathered} ((x)/(100))8=15 \\ (x)/(100)=(15)/(8) \\ (x)/(100)=(15)/(8) \\ (x)/(100)=(7)/(8) \\ x=(7)/(8)\cdot100 \\ x=87.5\text{ } \end{gathered}`
