Answer:
The effect that will happen on the net income is an increase in $6,000.
Explanation:
For this product, we have:
Price: $90.
Variable cost: $28
Allocated fixed cost: $18

We are all social creatures, some more than others, and we like to tell our friends about things that might be considered interesting, new, good, etc (a little gossip). We also know by now that advertisement is usually not 100% accurate, so we don´t fully trust it. When one of our friends tells us that they tried product X and it was great, we do trust them and probably will end up buying product X.
