During his vacation, Dalyn rents a small boat from a rental service that charges a flat fee of $30 plus $10 per hour (including taxes). The total charge comes to $90. Which equation can be used to calculate the number of hours, x, that Dalyn rents the boat?
create an equation and solve
The equation can be written as:
$30 + $10x = $90
To solve for x, we need to isolate it on one side of the equation.
Subtract $30 from both sides:
$10x = $90 - $30
The equation becomes:
$10x = $60
Divide both sides by $10:
x = $60 / $10
Simplifying the equation, we find:
x = 6
Therefore, Dalyn rents the boat for 6 hours.
