The ideal temperature inside a refrigerator is 37*5F plus or minus 3.5*F. Set up and solve an absolute value equation to find the high and low limits of the range of temperatures. Show your work.

And using properties of absolute value we got:

And adding 37.5 on both sides is given by:

Step-by-step explanation:

For this case we assume that the ideal temperature is given by

And for this case we know that the limits within 3.5 F within the ideal temperature so we can write this like that:

And using properties of absolute value we got:

And adding 37.5 on both sides is given by:
