Li Ling had some $2 notes and Anna had some $5 notes. After Li Ling
used of her notes and Anna used of her notes, they had the same
number of notes left. If they had $315 altogether in the end, how much
money did Li Ling have at first?

one day because their over eating or whenever it kicks in their body

hmmm

true, i think.

i checked and it seems the answer is, true.

absolute strength refers to the maximum force exerted by a body irrespective of body size. relative strength on the other hand is the force exerted by a body in relation to muscle size or body weight.

so the answer is: c. absolute strength measures strength regardless of your body size, while relative strength measures strength adjusted for your weight.
