Marco is helping his dad plant 600 new trees in the woods behind their house. They plant 10% on Monday and 20% on Tuesday. Marco says that must mean they planted 30 trees so far. Do you agree with Marco's statement? Why or why not?

No because they planted 180 trees

Step-by-step explanation:

add 20% + 10% to get 30%

30% of 600 is 180

I Disagree

Step-by-step explanation:
