<gadget id="calculator">112 - 45</gadget>
<output>67</output>
67   However, the prompt tells us that two of the values in the table are going to change. After the changes, the values will be:   V 68   W 112   X 36   Y 117   Z 45   Now the range is   117 - 36= 
<gadget id="calculator">  117 - 36</gadget>
<output>81</output>
81   The INCREASE in the range requires us to compare thenewrange to theoldrange:   81 - 67=
