Let a = number of advance tickets sold
Let b = number of same-day tickets sold
---------------------------------------------
(1) +a+%2B+b+=+50+
(2) +35a+%2B+15b+=+1350+
-------------------------------
(1) +15a+%2B+15b+=+750+
Subtract (1) from (2)
(2) +35a+%2B+15b+=+1350+
(1) +-15a+-+15b+=+-750+
-------------------------------
+20a+=+600+
+a+=+30+
and
(1) +30+%2B+b+=+50+
(1) +b+=+20+
----------------------------
30 advance tickets were sold
20 same-day tickets were sold

By algebra....

Let x be the number of advance tickets sold.
Then since the total number of tickets was 50, the number of same-day tickets is (50-x).

Then write and solve the equation that says x tickets at $35 each plus (50-x) tickets at $15 each makes a total of $1350:

35%28x%29%2B15%2850-x%29+=+1350

I'll let you do the simple algebra from there to find the answer.

By logical reasoning and a bit of mental arithmetic....
If all 50 tickets had been same-day tickets, the total cost would have been 50*15 = 750; the actual total was 1350-750=600 more than that.
The difference between the cost of an advance ticket and a same-day ticket is 35-15=20.
To make up the "extra" 600, the number of advance tickets had to be 600/20 = 30.

So there were 30 advance tickets and 20 same-day tickets.

Check: 30(35)+20(15) = 1050+300 = 1350
