Step-by-step explanation:

Hi,

So from Andre's perspective, if he receive money that would be positive (cuz that will be adding to his collection) whereas, if he has to give money away that would be negative (cuz he would have to pay out of his pocket).

Think about it like this, people generally feel positive when they receive money and feel negative when they give away money. Apply this same concept.

Therefore,

A) Andre received money so = $25

B) Andre earned money so = $18

C) Andre had to give money away to buy the book so = - $10

D) Zero (0) would mean that he did not gain or lose any money.
