tickets sold

Question

Suppose some of the tickets sold for $8 and some sold for $5 ? What were the total ticket sales ? Write an equation to solve this problem.

Answer 1

Let x = the number of $8-tickets sold

     y = the number of $5-tickets sold

 

The total number of tickets sold is:   x+y

 

Realize:

  the dollars = (dollars per ticket)*(number of tickets sold)

 

So,

  the total dollars for all tickets sold is:   8x + 5y     [eq1]

 

Usually, this type of problem gives a value for (x+y) so that you may solve for either x or y than substitute that value into [eq1] and solve for the other variable.
