Question

4) A baby weighed 7.2 pounds at birth and 9.0 pounds at the age of onemonth. What was the percent increase?

Answer 1

25%

Step-by-step explanation:

The percent of increase can be calculated using the following equation

`\frac{\text{ Final value - Initial Value}}{\text{ Initial Value }}*100`

So, replacing the final value by 9 pounds and the initial value by 7.2 pounds, we get:

`(9-7.2)/(7.2)*100=(1.8)/(7.2)*100=0.25*100=25\text{ \%}`

Therefore, the percent of increase is 25%
