Kevin has a tree growing in his garden that is currently 180 inches tall. That is 50% taller than it was when he planted it there. How tall was the tree, in feet, then? Let's think first. Chain of thought:
User
Since it is 50% taller, then 180 inches is 100% + 50% = 150% of its height then. So each 1% is equal to 180 / 150 = 1.2 inches. So, its height then was 1.2 x 100% = 120 inches. Since 1 foot is equal to 12 inches, then 120 inches is equal to 120 / 12 = 10 feet.
Therefore, the answer is 10.
