A thermostat is set so that the temperature in laboratory freezer stays within 2.5 degrees F of 2 degrees F. Write and solve an absolute value equation to find the maximum and minimum temperatures in the freezer.

The absolute value gives the positive value of any given number inside the symbol. The absolute equation is,

2.5 = I d - 2I

The values of d can be calculated through,

2.5 = d - 2

d = 4.5

Also,

-2.5 = d - 2

-2.5 + 2 = d

d = - 0.5

Thus, the maximum value of the temperature is 4.5 and the minimum value of the temperature is - 0.5.
