An uncooked gingerbread cookie is y centimeters long. After it is baked, the length of the

cookie increases by 25%. Which expression best represents the new length of the

cookie?

A. 0.25y

B. 0.75y

C. 1.25y

D. 12.5y

I think the answer is C

Step-by-step explanation:

If you have a normal ginger bread cookie, its full size would be 100%. So, if you add the first 25%, 1.25%

C - 1.25 y

Step-by-step explanation:

A is if it shrunk to a quarter of its original length

B is if it decreased by a quarter

C is correct

D is if it grew by 1150 %

The full length is 1 y, so to increase it by 25% (0.25), then it would be 1.25 y.
