Question

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

represents the cost of a ticket. How much is one ticket?
$3.00
$4.00
$9.00
$15.00

Answer 1

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
