Answer: 7 days.
Explanation:
Let the number of days the Ramirez family rent the cabin be represented by x.
Since the rental company charged $105 per day and charged a $200 cleaning fee and the family spent $935, this can be represented in an equation as:
$200 + $105x = $935
200 + 105x = 935
105x = 935 - 200
105x= 735
x = 735/105
x = 7
The Ramirez family rent the cabin for 7 days
