Algebra.Com's Answer #173159 by jsmallt9(3758) ![]() You can put this solution on YOUR website! Average = Total/(Number of scores) \n" ); document.write( "Therefore, after multiplying both sides by (Number of Scores): \n" ); document.write( "Average*(Number of scores) = Total \n" ); document.write( "With Juan's average on 5 tests this becomes: \n" ); document.write( "88*5 = Total \n" ); document.write( "440 = Total \n" ); document.write( "So the total of Juan's 5 tests must be 440 in order for his average to be 88. If we are looking for the lowest possible score on one test then the other 4 tests would have to be the highest possible (which is 100). Four tests of 100 add up to 400. So the fifth test would have to be a 40 in order for the average to be 88. Anything less than a 40 would mean that there would be no way for all 5 tests to add up to 440. \n" ); document.write( " |
