A boating club rents sail boats for $60 for the first hour and $20 for each additional hour. When you return your boat, your fee is $140. Write and solve an equation to find how many hours you kept the boat.

Let x = the number of hours you rented the boat

$140 = $20x + $60.

Subtract 60 from both sides

$80 = $20x

Divide each side by 20.

4 = x.

You rented the boat for 4 hours
