They were selling adult tickets for $4.00 and $2.50 for students. In total they sold 125 tickets. How much of each ticket did they sell

Question

How to solve this un know equation.

Answer 1

Let m and n be the NUMBER of tickets sold at $4 and $2.50, respectively.

Then m + n= 125.

Gross revenue = ? = 4m + 2.5 n.

 

this is two equations but the total $ was not given, so the second equation is incomplete.

Until the $? is given, you are stuck.
