$21\cdot 36=(20+1)(30+6)=600+120+30+6 = 756$

A baby weights 18 pounds at her four month appointment. Six months later she weights 24 pounds. By what percentage did the baby’

Anna11 [10]

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 = $=\dfrac{\text{Increase in baby's weight}}{\text{previous weight}}\times100$

$\\\\=\dfrac{6}{24}\times100=25\%$

Hence, the percentage increase in baby's weight = 25%
