Let's presume that Sarah takes tests that have a maximum score of 100 points. So her 92.5
\n" ); document.write( "average means that on the three tests she took she scored an average of 92.5 points
\n" ); document.write( "each time.
\n" ); document.write( ".
\n" ); document.write( "Since Sarah has averaged 92.5 on three tests, on these three tests she has gotten a total
\n" ); document.write( "of 92.5 times 3 or 277.5 points.
\n" ); document.write( ".
\n" ); document.write( "If she is to average 94 points on 4 tests she will need 94 times 4 = 376 points.
\n" ); document.write( ".
\n" ); document.write( "Therefore, on the next test she will have to score enough points to take her total score from
\n" ); document.write( "277.5 points to 376 points.
\n" ); document.write( ".
\n" ); document.write( "Find the answer by subtracting 277.5 from 376 and you find that she will need 98.5 points
\n" ); document.write( "out of 100 (or 98.5 percent) on her next exam.
\n" ); document.write( ".
\n" ); document.write( "Hope this helps you to understand the problem. \n" ); document.write( "
