On a typical Saturday 5 pm, you were sitting on the couch watching the TV while Adrianna was upstairs listening to music. Suddenly, the doorbell rang, and your mother answered it. In stepped Nicole, the babysitter for the night, and her younger sister Cheryl (who was about 9). Your parents then exited to go on their night.

Nicole was wearing jeans, a sweater, and brown suede boots. Cheryl was wearing a skirt, t-shirt and blue flip-flops. Cheryl immediately went upstairs to play with Adrianna.

What happened to your height before Cheryl stepped into the living room?
