30000= 100%
x=5%
30000/x=100/5
<span>(30000/x)*x=(100/5)*x
</span>30000=20*x
30000/20=x
x=1500
5%of 30000 is 1500

Answer:
Option C
Step-by-step explanation:
Zeros of a function are also called as x-intercepts of a function, which means where the graph/function intersects the x-axis.
In the image we see the graph intersects the x-axis at three points
x=0 , x=2 , x=4 so our answer is option C
