Answer:

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.
