A total of 429 tickets were sold for the school play. they were either adult tickets or student tickets. the number of student tickets sold was two times the number of adult tickets sold. how many adult tickets were sold? adulttickets
Let's say adult tickets = x and student tickets = y
(1) x + y = 429
The number of student tickets sold is twice the number of adults tickets sold, therefor y = 2x Now if we substitute this into equation (1), we get: x + 2x = 429 3x = 429 x = 143 Therefor the number of adult tickets sold is 143
