<PRE><B>Question 1015568</B>
On a 100-mile hike, Mike walks 15 miles the first day, 10% of what is left the next day and 0.2 of the total the following day. What percent of the hike has Mike left to walk? 
----------
1st day:: 15 miles
2nd day:: 0.10*85 = 8.5 miles
3rd day:: 0.2(100-15-8.5) = 0.2(76.5) = 15.3 miles
-----
Total walked (15+8.5+15.3) = 38.8 miles
-----
Distance left:: 100-38.8 = 61.2 miles
---------
Ans: Percent left:: 61.2%
