The cost of performance tickets and beverages for a family of four can be modeled using the equation 4x + 12 = 48, where x
Hunter-Best [27]

For this case we give as data the following equation:

4x + 12 = 48

Where "x" represents the cost of a ticket.

By clearing the value of "x" of the equation we can know the cost of a ticket.

If we subtract 12 from both sides of the equation, we have:

4x = 48-12\\4x = 36

If we divide between 4 on both sides of the equation:

x = \frac {36} {4}\\x = 9

Therefore, the cost of a ticket is $ 9.00
