Azoo has 15 emperor penguins the emperor penguins make up 30% of all the penguins at the zoo. how many penguins live at the zoo

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!!!

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.
