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

C) $9.00

Explanation:

1. You're trying to find the value of x.
2. 4x + 12 = 48 Subtract 12 from both sides to get:
3. 4x = 36 Then, divide each side by 4 to get:
4. x = 9

Answer 2

For this case we have that the cost of a ticket is given by the variable "x". We have the following equation:

`4x + 12 = 48`

By clearing "x" we have:

We subtract 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`

Then, a ticket costs $ 9.00
