A random output something like:
<pre>Price for 0.73, is: 0.82
Price for 0.29, is: 0.44
Price for 0.25, is: 0.38
Price for 0.52, is: 0.66
Price for 0.66, is: 0.78
Price for 0.23, is: 0.38
Price for 0.62, is: 0.74
Price for 0.26, is: 0.44
Price for 0.70, is: 0.78
Price for 0.69, is: 0.78
Price for 0.39, is: 0.54</pre>
