Question

The school production of​ 'Our Town' was a big success. For opening​ night, 497 tickets were sold. Students paid ​$2.50 ​each, while​ non-students paid ​$4.50 each. If a total of $ 1450.50 was​ collected, how many students and how many​ non-students attended?

Answer 1

So, what did they tell you?
s+n = 497
2.50s + 4.50n = 1450.50
Now just solve for s and n.
