Elliot collects miniature toy cars. He wants to fill 4 display cases. Each display case holds 15 cars. He has 33 cars now. He is able to buy 3 more cars every month with the money he saves. How many more months will it take for Elliot to have enough cars to fill all 4 display cases? (1 point) Enter your answer in the box. Elliot will have enough cars to fill 4 display cases in months.
Elliot needs a total of 4 display cases * 15 cars per display case = <<4*15=60>>60 cars.
He still needs 60 cars - 33 cars = <<60-33=27>>27 more cars.
At a rate of 3 cars per month, Elliot will need 27 cars / 3 cars per month = <<27/3=9>>9 more months. Answer: \boxed{9}.
