Hello!
You can break this down
12 times the sum of 3 and c
This can be written as 12(3 + c)
is greater than 27
12( 3 + c) > 27
This can be simplified to 36 + 12c > 27
The answer is 12(3 + c) > 27 or 36 + 12c > 27
Hope this helps!
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!!!
