**Ms. Sue**, Tuesday, April 22, 2008 at 10:05pmHow many people attend the movie?

**Reiny**, Tuesday, April 22, 2008 at 10:24pmThe persons getting a free ticket would be numbers 12,24,36,48,60,72,...

the persons getting free popcorn would be

numbers 15,30,45,60,75,...

isn't 60 the LCM of 12 and 15?

so the people getting both would be number

60,120,...

So, Ms. Sue pointed out, we would have to know how many people attended to answer the question.

I am sure you can take it from here.
