Give the step-by-step reasoning process and then the final answer. Annie has 6 barrettes, twice as many scrunchies as barrettes, and three fewer bobby pins than barrettes. What percentage of her hair decorations are bobby pins, rounded to the nearest percent?
First find the total number of scrunchies: 6 barrettes * 2 = 12 scrunchies. Then subtract three fewer bobby pins than barrettes 6 - 3 = 3 bobby pins. Then add the number of each type of hair decorations to find the total number: 6 decorations + 12 decorations + 3 decorations = 21 decorations. Then divide the number of bobby pins by the total number of decorations and multiply by 100% to express the answer as a percentage: 3 bobby pins / 21 decorations * 100% = 14.28 which rounds down to 14%.
The final answer: 14.
