I need assistance on the following problem: Rod's quiz grades are 73, 75, 89, & 91. What scores on a fifth quiz will make his average quiz grade at least 85? Translate to an equality. I came up with:
\n" ); document.write( "X + 73 + 75 + 89 + 91 = greater then 85
\n" ); document.write( "NO NOT EQUAL TO 85 BUT 85*5=425..SINCE 85 IS AVERAGE SCORE TOTAL MARKS IN 5 TESTS IS 5*AVERAGE
\n" ); document.write( "X + 328 >=425
\n" ); document.write( "X>=425-328=97 IS THE ANSWER \r
\n" ); document.write( "\n" ); document.write( "greater then 85
\n" ); document.write( "???????????
\n" ); document.write( "X = 97
\n" ); document.write( " \n" ); document.write( "
