Hey there!

a.) 1 inch

beginning = 2; end = 3; difference of 1

b.) December, because the length was, let's say, 2, then it went down 1 (so we're at 1), then went up 3 (4), then went down

c.) in December

Hope it helps, have a great day!

Step-by-step explanation:

a.total change in my hair =2-1+3-4+3=3inches

b.my hair is longer on December because the length of my hair is 3inches but 2inches in January.

c.my hair is longest as on December because the length of my hair is longer than on other month.

the answer is 11.2 (i know i’m late)
