Question 1189423
.
A recent survey of college students on a big campus was conducted to find students' 
preferred method of getting to class. The results showed that 35% of students walk to class, 
20% take the bus, 25% ride a bike, and 15% drive; the remaining students rollerblade to class. 
If each student preferred only 1 method of getting to class and 75 students preferred 
rollerblading, how many students were surveyed?
~~~~~~~~~~~~~~~


<pre>
35% + 20% + 25% + 15% = 95%.


So, 75 students, who prefer rollerblading, comprise 5%.


Therefore,  {{{75/0.05}}} = {{{7500/5}}} = 1500 sudents were surveyed.    <U>ANSWER</U>
