In a spelling bee 50% of the students were eliminated after the first round. Only 1/3 of the remaining students were still in the contest after the second round. If 24 students were still in the contest after the second round, how many students began the contest?

x = starting number

x * .5  = number after first round

 

(x *.5) * 1/3   = after the second round = 24

 

x * .5  * 1/3 = 24         solve for 'x' to find starting number of students
