Question: Ariana heard the news that a new grocery store had opened up in their town, so she decided to buy some flowers for her house. She bought a bunch of 40 flowers, 2/5 of which were roses, 10 were tulips, and the rest were carnations. How many carnations did she buy? Think carefully first, then make a decision:
The number of roses in the bunch is 2 / 5 * 40 flowers = 16 flowers. The total number of roses and tulips is 16 flowers + 10 flowers = 26 flowers. There were 40 flowers - 26 flowers = 14 carnations. So the answer is 14.
