Question: The New York City Council bought 200 streetlights to modernize its squares. But they don't have enough squares to use all the streetlights bought. Knowing that there are 15 squares in New York and that each park will have 12 new streetlights bought by the city council, how many unused streetlights will remain?
Answer: So the total number of streetlights that will be used is 15 squares * 12 streetlights / square = 180 streetlights. There will be 200 streetlights - 180 streetlights = 20 streetlights unused. The answer is 20.
