I need to define a variable, write an equation and solve the problem. Adults' tickets cost $5 and students' ticket cost $2. If 295 tickets were sold and a total of $950 was collected, how many students' tickets were sold?

Yes, and what did you try?

I'll define them for you.

Let x be the number of students' ticket.
Let y be the number of adults' ticket.

Can you complete it now? :)

5x+2(295-x)=950
Number of tickets sold cost 5x+590-2x=950
Adults x $5 3x+590=950
------------------------------------------------------------------------------- -590 -590
Kids 295-x $2 ----------------------
3x=360
295 tickets sold in total $950 total --- ---

I x=120=number of adult tickets sold I
I 295-x=175=number of kids tickets sold I
