Tuition paid [#permalink]  17 Apr 2011, 11:16
At a certain state university last term, there were p students each of whom paid either the full tuition of x dollars or half the full tuition. What percent of the tuition paid by the p students last term was tuition from students who paid the full tuition?

(1) Of the p students, 20 percent paid the full tuition.
(2) The p students paid a total of $91.2 million for tuition last term. This had already been posted, but none of the explanations are great. Please help. _________________ petrifiedbutstanding Math Forum Moderator Joined: 20 Dec 2010 Posts: 2026 Followers: 145 Kudos [?]: 1259 [0], given: 376 Re: Tuition paid [#permalink] 17 Apr 2011, 11:32 petrifiedbutstanding wrote: At a certain state university last term, there were p students each of whom paid either the full tuition of x dollars or half the full tuition.
