The world record for longest fingernails is 26 inches. Sandy, who just turned 12 this month, has a goal for tying the record. Her fingernails are 2 inches long. Her fingernails grow at a rate of one-tenth of an inch per month. How old will she be when she achieves the world record? Give me reasons, before answering the question

Sandy's fingernails will grow a total of ( 0.1 ) * 12 = 1.2 inches per year. To achieve the world record, Sandy needs to grow her fingernails a total of 26 - 2 = 24 inches. It will take her a total of 24 / 1.2 = 20 years. Sandy will be 12 + 20 = 32 years old when she achieves the world record. So the final answer is 32.
