<PRE><B>Question 1193912</B>
&lt;br&gt;
The other tutor apparently doesn&#39;t know that in many parts of the world the &quot;,&quot; is used instead of &quot;.&quot; as the &quot;decimal point&quot;....&lt;br&gt;
Let&#39;s change the format to use the more common &quot;.&quot;&lt;br&gt;
The first 5.9180 KL costs R2.46; after that the cost is R6.52 for every 3.1640 KL.&lt;br&gt;
R340-R2.46 = R337.54  (cost of the water after the first 5.9180 KL)&lt;br&gt;
R337.54/R6.52 = 51.77  (number of groups of 3.1640 KL after the first 5.9180 KL)&lt;br&gt;
51.77*3.1640 = 163.8  (number of KL after the first 5.9180 KL)&lt;br&gt;
5.918+163.8 = 169.718  (total number of KL)&lt;br&gt;
ANSWER: 169.718 KL&lt;br&gt;
