<font face="Times New Roman" size="+2">


The average of 5 numbers is the sum of the 5 numbers divided by 5.  So the total of the 5 numbers must be 5 times the average.  Add the given scores, then subtract that total from the product 5 times 90 to get the minimum score that will give an A grade.  The upper end of the range is given as 100.
