Below is an instruction that describes a task. Write a response that appropriately completes the request in English. Please answer in English.

### Instruction:
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?

### Response:
Max fills 30 * 2 = <<30*2=60>>60 water balloons
Zach fills 40 * 3 = <<40*3=120>>120 water balloons
Together they fill 60 + 120 = <<60+120=180>>180 water balloons
After the balloons pop, there are 180 - 10 = <<180-10=170>>170 water balloons
Max and Zach have a total of 170 water balloons
#### 170
