#### Answer:

Any number greater than 40.5

#### Explanation:

The first term can be written as N + 81
The second term can be written as 3 N

The inequality then can be written as

N + 81 > 3N Subtract N from both sides giving
$N - N + 81 > 3 N - N$ This results in

$81 > 2 N$ Divide both sides by 2

$\frac{81}{2} > 2 \frac{N}{2}$ ( since dividing the > by a positive does not change the direction of the sign it remains > ) This results in

$40.5 > N$ or

$N < 40.5$
