a. What is the total change in your hair length at the end of the year?
b. Is your hair longer in January or December? Explain your reasoning.
c. When is your hair the longest? Explain your reasoning.

Answer 1

3

December. total change in December is greater than change in January. 3 is greater than 2

August. the total change in hair growth is 4.

Explanation:

total change in hair length = 2 - 1 + 3 - 4 + 3 = 3

My hair is longer in January .

total change in hair length in February = 2 -1 = 1

total change in hair length in August = 1 + 3 = 4

total change in hair length in September = 4 - 4 = 0

total change in hair length in December = 0 + 3 = 3

My hair is the longest in August because that is the month that has the highest change in hair length
