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 > 3N - N# This results in

# 81 > 2N# Divide both sides by 2

# 81/2 > 2N/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#
