(i'm not asking anyone to actually do this for me, I just need guidance/someone to explain to me how to do this)

Answer 1

Add up all the numbers, subtract that amount from 130, and see if it is too little or too much. If it is too much then find items repeated and suggest to get rid of them.

Answer 2

And for equation just put what you had to subtract.

Answer 3

like say n is the amount, 130-n=?

Answer 4

does that make sense to you?
