A zoo has 15 emperor penguins The emperor penguins make up 30% of all the penguins at the zoo. How many penguins live at the zoo
r-ruslan [8.4K]

Let x + 15 = total penguins

15/ (x +15) = .30

15 = .30x + 4.5

.30x  = 10.5

x = 35

Total penguins = 15 + 35 = 50

Double Check

15 / 50 * 100 = 30%  Correct!!!
