when you first move into your current house, you noticed that a tree outside had a height of 63 inches. You noticed that after 3 years, the height was 72 inches. Predict how tall the tree will be after 20 years.
72-62=9 (grow 9 inches in 3years) In a year it grows 3 inches (9/3) Find how much it grows in 20 years: 3*20=60 inches Then just add the 60 inches to the original height er 63+60=123 inches
