Answer:

50 penguins

Explanation:


\bold{METHOD\ 1}:\\\\\begin{array}{ccc}15&-&30\%\\x&-&100\%\end{array}\qquad\text{cross multiply}\\\\30x=(15)(100)\\30x=1500\qquad\text{divide both sides by 30}\\\boxed{x=50}


\bold{METHOD\ 2}:\\\\\begin{array}{cccc}15&-&30\%&\text{divide both sides by 3}\\15:3&-&30\%:3\\5&-&10\%&\text{multiply both sides by 10}\\(5)(10)&-&(10\%)(10)\\50&-&100\%\end{array}
