there are 5 days so the sum of temperature can be 55*5= 
<gadget id="calculator">55*5</gadget>
<output>275</output>
275   lowest is 45. to find the maximum range we can say the temperature was the lowest for 4 of the 5 days   so   4*45= 
<gadget id="calculator">  4*45</gadget>
<output>180</output>
180.   on the fifth day it is   275-180= 
<gadget id="calculator">  275-180</gadget>
<output>95</output>
95   range is therefore 95-45=40   answer 40
<result>C</result>
