Lizzy: Marcia's hair is 24" long at the beginning of the school year. She cuts half of her hair off and lets it grow out 4 more inches. She then cuts off another 2" of hair. How long is her hair?.
Me: Hmmm, let me think. I think this is the detailed solution:
User
Her hair was 24" long and she cut half off so she cut 24 / 2 = 12 inches. Her hair was 24" long and she cut 12" off so she has 24 - 12 = 12 inches left. She has 12" of hair and lets it grow 4 more inches for a total of 12 + 4 = 16 inches. She has 16" and cuts off 2 more inches which leaves her hair 16 - 2 = 14 inches long. Final answer: 14.
