Question

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

Answer 1

Answer: 44

Step-by-step explanation:

hey there person

So 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.
