Question 547367
 210 people attended a school carnival. The total dollars earned at the carnival was $710. Tickets for regular admission were $5, student tickets were $3, and children under 5 were $1. The number of regular admissions sold was 10 more than twice the number of child tickets sold. How many of each type of ticket were sold? So far I got two equations
--------------------------
r + s + c = 210
5r + 3s + c = 710
r = 2c + 10
------------------
Makes it easy to sub for r
Can you finish it?
