Sam must have an average of 70 or more in his summer course to obtain a grade of C. His first three test grades were 75,63, and 68.
\n" ); document.write( "Write an inequality representing the score that Sam must get on the last test to get a C grade. \r
\n" ); document.write( "\n" ); document.write( "Let \"x\" be the minimum score Sam needs to make the 70 average.\r
\n" ); document.write( "\n" ); document.write( "EQUATION:
\n" ); document.write( "(75+63+68+x)/4>=70
\n" ); document.write( "206+x>=280
\n" ); document.write( "x>=74
\n" ); document.write( "Sam needs a score of at least 74 to achieve an average of 70 on the 4 tests.
