If the air pressure is within 4 inches of the other town's 29 inches, then the pressure in this town must be between 25 and 33 inches. Call the pressure in this town P. Thus
25 <= P <= 33

The average air pressure in another town is 29 inches but the actual pressure is within 4 inches of the average. Write and solve an inequality to find the range of air pressure in this town.
==============
29 - 4 <= P <= 29 + 4
25 <= P <= 33

PS 4" is a lot of pressure difference.
A pressure of 27" (~ 2.5" below typical) is found in hurricanes.
------------------
Category 1
Hurricane has a central barometric pressure of 28.94 inches or more and winds of 74 to 95 mph. The storm is accompanied by a 4 to 5 foot storm surge and causes minimal damage
Category 2
Pressure 28.5 inches to 28.93 inches, winds from 96 mph to 110 mph, storm surge 6 to 8 feet, damage moderate.
Category 3
Pressure 27.91 inches to 28.49 inches, winds from 111 mph to 130 mph, storm surge 9 to 12 feet, damage extensive.
Category 4
Pressure 27.17 inches to 27.90 inches, winds from 131 mph to 155 mph, storm surge 13 feet to 18 feet, damage extreme.
Category 5
Pressure less than 27.17 inches, winds greater than 155 mph, storm surge higher than 18 feet. Damage Catastrophic.
