$1.80(X)+$30.00= $264.00
x=$130.00
not sure if you only needed the equation or the answer

Answer 2

Marni danced for 130 minutes.

Explanation:

Let x equal the number of minutes Marni danced.

Marni raised $30 plus $1.80 per minute that she danced.

She raised a total of $264.

The expression that completes the equation to determine the total amount of minutes Marni danced is :

`264=30+1.80x`

To know the number of minutes did Marni dance, we will find x from the above equation.

`264=30+1.80x`

=>
`1.80x=264-30`

=>
`1.80x=234`

x = 130 minutes.

Therefore, Marni danced for 130 minutes or 2 hours 10 minutes.
