Answer provided by our tutors
let 'x' represent the number of $10 tickets sold, then 'x+202' represents the number of $20 tickets sold and '503-x-(x+202)' represents the number of $30 tickets sold
9410 = 10x + 20(x+202) + 30(503-x-(x+202))
solving for 'x' we have x=122
122+202 = 324
503 - 324 - 122 = 57
57 $30 tickets were sold
324 $20 tickets were sold
122 $10 tickets were sold
