Answer:
4.8
Explanation:
first you figure out how much she grows in a month, so you divide 2 by 5, which is 0.4 inches. then you simply just multiply 0.4 by 12, because there are 12 months in a year and we are looking for how much her hair grew in one year. to check our answer, we can just add 2 + 2 which is 4, which is how much her hair grew in 10 months, which is very very close to our answer.
