In this question, we're trying to find how many hours Maria can rent the boat for.
We know that the boat rental costs $60 per hour
We also know that she has to pay a one-time fee of $10 for a safety course
Turn this into a equation:
y = 60x + 10
However, she doesn't want to spent no more than $230. Add that to your equation
230 = 60x + 10
Solve the equation to see how many hours she can rent the boat for.
230 = 60x + 10
Subtract 10 from both sides
220 = 60x
Divide both sides by 60
3.67 = x
Since the boat can ONLY be rented by whole hours. With the money Maria has, she can only rent the boat for 3 hours.
Answer:
3 hours
