Cody and Tyler were once the same height. Since then, Tyler's height has increased by 20%, while Cody has grown half as much. If Tyler is 4 feet tall now, how many inches tall is Cody now?
Question
Answer:
Answer: 44Step-by-step explanation:hey there personSo Tyler is currently 4*12 = 48 inches tall. He is now 100% + 20% =120% of his original height, so his current height is 120/100 = 6/5 of his original height. This means his original height is 5/6 of his current height, so his original height was 5/6(48)=40 inches. Tyler grew 48-40=8 inches, so Cody grew 4 inches, to 40+4 = 44 inches.ALL CREDIT GOES TO AOPS ACADEMY!!!!!!!!!!!!!!!!!!!:DI'm to lazy to explain everything with my own words
