Answer: 25%
Step-by-step explanation:
Given : Previous baby's weight = 18 pounds
New baby's weight = 24 pounds.
Increase in weight = New weight -Previews weight
=24 pounds - 18 pounds =6 pounds
Percentage increase in baby's weight =[tex]=\dfrac{\text{Increase in baby's weight}}{\text{previous weight}}\times100[/tex]
[tex]\\\\=\dfrac{6}{24}\times100=25\%[/tex]
Hence, the percentage increase in baby's weight = 25%
