An interval as a set of numbers. Numbers = endpoints.
Build interval notation
We get interval notation by saying 12a>3.60
Since our variable of a has a coefficient of 12 Divide each side of the inequality by 12
12a
12
>
3.60
12
a>0.3 ←Use this expression going forward

Build the interval notation for a:
No equal sign translates to (. Do not include the number 0.3
Based on the > you entered, the right side of the interval notation will extend to positive infinity, which is denoted as +∞
