求助!一道GMAT数学题
If an organization were to sell n tickets for a theater production, the total revenue from ticket sales would be 20 percent greater than the total costs of the production. If the organization actually sold all but 5 percent of the n tickets, the total revenue from ticket sales was what percent greater than the total costs of the production?
正确答案说是14%, 但不知道是怎么求出来.我以为是20%*95%=19%,不知道正确的公式应该是什么呢?

一个机构要为一个Theater production销售N张Tickets(n)
售票总收入R=n*p（p为单价)是成本的120%,也就是R=C*120%
如果只卖出95%,那么修正之后收入就是S=R*95%
R=C*120%
S=R*95%->R=S/(95%)
S/(95%)=C*120%
S/C=95%*120%=1.14
所以1.14-1=14%
就得到答案结果了.

现在是已经花了N张票的成本了那么售出了95% 实际收入0.95*1.2=1.14 多出了0.14 即14%

能不能换成中文，看不懂啊
