Question 330957
<font face="Garamond" size="+2">


Remember how you calculate an average.  You add up the numbers and divide by the number of numbers.  In order for the average of three scores to be 77, the sum of the three scores must be 3 times 77.  Subtract 77 plus 80 from 3 times 77 to get the minimum score possible for a 77 average.
