<PRE><B>Question 1188914</B>
&lt;br&gt;
My guess is that it is the recursive formula you don&#39;t understand.  I will explain that; then you can answer the questions.&lt;br&gt;
If you then still need more help, re-post the question telling us WHAT it is about the problem that you don&#39;t understand.&lt;br&gt;
The recursive formula is&lt;br&gt;
tn = tn-1 + 0.75; t1 =8&lt;br&gt;
I much prefer to write it as a function, like this:&lt;br&gt;
t(n) = t(n-1)+0.75; t(1) = 8&lt;br&gt;
In that form, t is the total taxi fare and n is the number of kilometers traveled.  The recursive formula then says two things:&lt;br&gt;
(1) The cost for traveling n kilometers is the cost for traveling (n-1) kilometers, plus 75 cents -- in other words, each additional kilometer costs 75 cents more; and&lt;br&gt;
(2) The cost of traveling 1 kilometer is $8&lt;br&gt;
