5x - 150 - 3x = 230
2x = 80
x = 40

Yes.
OpenStudy (anonymous):
so the answer is 40 $5 tickets and therefore 10 $3 tickets. the correct answer to the question asked is 10, not 40
OpenStudy (anonymous):
How'd you get 10?
OpenStudy (anonymous):
you could either solve
\[3x+5(50-x)=230\] or reason that if there are 40 $5 tickets sold and the total is 50 then there must be 10 sold at $3
OpenStudy (anonymous):
Yeah. okay thanks!
