The average of temperatures at noontime from Monday to Friday is 60; the lowest one is 45, what is the possible maximum range of the temperatures? Choose one.
A) 20	B) 25	C) 40	D) 45	E) 75
there are 5 days so the sum of temperature can be 60*5= 
<gadget id="calculator">60*5</gadget>
<output>300</output>
300   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   300-180= 
<gadget id="calculator">  300-180</gadget>
<output>120</output>
120   range is therefore  120-45= 
<gadget id="calculator"> 120-45</gadget>
<output>75</output>
75   answer 75
<result>E</result>
