My question is: Max fills up water balloons for 30 minutes at a rate of 2 water balloons every minute. Max’s friend Zach fills up water balloons for 40 minutes at a rate of 3 water balloons every minute. In the process, 10 of the water balloons pop on the ground. How many filled water balloons do Max and Zach have in total? Your thoughts:

Max fills 30 * 2 = 60 water balloons. Zach fills 40 * 3 = 120 water balloons. Max and Zach have a total of 60 + 120 - 10 = 170 water balloons. The final answer: 170.
