Let x be the number of the $25 tickets.
Then the number of the $15 tickets is (1700-x).
The "money" equation is
25x + 15*(1700-x) = 33000 dollars.
Simplify and solve for x:
25x + 25500 - 15x = 33000 ====> 10x = 33000 - 25500 = 7500 ====> x = = 750.
Answer. 750 tickets by $25 and the rest 1700-750 = 950 tickets by $15.
Check. 750*25 + 950*15 = 33000. ! Correct !
Solved.
