A thermometer comes with a guarantee that the stated temperature differs from the actual temperature by no more than 1.5 degrees Fahrenheit. Write and solve an equation to find the minimum and maximum actual temperatures when the thermometer states that the temperature is 87.4 degrees Fahrenheit.
---------------------------------------
Equation:
|x-87.4| <= 3
---
-3<= x-87.4 <= 3
Add 87.4 along the lines to get:
84.4 <= x <= 90.4
min = 84.4
max = 90.4
=====================
