Let &lt;i&gt;&lt;b&gt;x&lt;/b&gt;&lt;/i&gt; represent the number of problems on the test.  Then &lt;b&gt;&lt;i&gt;x&lt;/i&gt;-9&lt;/b&gt; represents the number of problems correctly answered.  Since the score on the test was 44%, &lt;b&gt;.44&lt;i&gt;x&lt;/i&gt;&lt;/b&gt; also represents the number of problems correctly answered.


So:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ x - 9 = 0.44x]


Solve for &lt;i&gt;&lt;b&gt;x&lt;/b&gt;&lt;/i&gt; and round to the nearest integer.
