Hello!
First we will find the cost of 3 hats.
11.99(3)=35.97
Now we subtract this from 60.
60-35.97=24.03
Therefore, we have the inequality below.
7.5p≤24.03
Now we solve our inequality for p, just like an equation. We will divide both sides by 7.5
p≤3.204
This leaves us with our final answer being C.
I hope this helps!
