Hello! Could you please explain how to answer Question #16 from Section #3 from official practice SAT test #5? Thank you in advance!
She only has to take the water safety course ($10) once, so you can really think about her budget as the $280 the question provides minus the cost of the safety course: $280 – 10 = $270.
The question is asking how many whole hours Maria can rent the boat, at $60 per hour, and stay within her budget. In other words, how many times does 60 go into 270?
<– Too big!
Therefore, Maria can afford to rent the boat for 4 hours—the answer is 4.
