A gardener is planting two types of trees
Type a is a 7 feet tall grows at a rate of 7 inches per year
Type b is 10 feet tall and grows at a rate of 4 inches per year
Algebraically determine exactly how many years it will take for these trees to be the same height
The taller tree is 3 feet, or 36 inches taller. The shorter tree is reducing that height difference by 7 -4 = 3 inches per year. It will take 36/3 = 12 years for the trees to become the same height.
