Q: Carla is making smoothies. If she uses 500 ml of watermelon puree and 100 ml of cream, how many 150 ml servings can she make?

Question: Zainab earns $2 an hour passing out flyers at the town square. She passes out flyers on Monday, Wednesday, and Saturday each week, for 4 hours at a time. After passing out flyers for 4 weeks, how much money will Zainab earn?

[Question]Rhonda, Sally, and Diane are members of their school's track team. The three of them run the 600-meter relay race together. Rhonda runs the first 200 meters of the race, Sally runs the second 200 meters of the race, and Diane runs the final 200 meters of the race. Rhonda can run 200 meters in 24 seconds.
