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

$9.00

Explanation:

4x + 12 = 48 - First, subtract 12 from both sides.

4x = 36 - Then, divide each side by 4 to get x by itself.

x = 9 - After getting x by itself, we see that x = 9, so one ticket will

cost $9.00

Answer 2

For this case we have the following equation:

`4x + 12 = 48`

Where the variable "x" represents the cost of a performance ticket.

Clear "x" of the equation to know the cost of a ticket.

Subtracting 12 on both sides of the equation:

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

Dividing between 4 on both sides of the equation:

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

So, the cost of a ticket is $ 9.00
