During his vaccination, Daylen rents a small boat for rental services that charges a flat fee of $30 plus $10 per hour including tax. Total charge comes to $90 which equation can be used to calculate the number of hours X they’ll rents the boat.

Let the number of hours Daylen rents the boat be represented by X.

The total charge for renting the boat is a flat fee of $30 plus $10 per hour, including tax. Therefore, the equation can be represented as:

Total charge = Flat fee + (Hourly fee * Number of hours)

$90 = $30 + ($10 * X)

This equation can be used to calculate the number of hours, X, that Daylen will rent the boat.
