A tree in Debra's backyard is 64 centimeters high. The tree grows 7 centimeters each month. Within the first month of planting it, Debra trimmed 6 centimeters off its height. She has not trimmed the tree since then. How long has the tree been growing?
It should be 10 months because if the tree grows 7 centimeters each month then in 10 months it'll be 70 and if she removes 6 inches off that'd be equivalent to 64 centimeters high
