Answer:
An increase of $3,400
Step-by-step explanation:
Well as you can see in the text, the variable cost of producing the goods is $18, and the shipping cost per unit would be $2, we can ignore fixed cost since those are already covered by the units sold in our regular market, so the total cost would be $20 with the variable and shipping cost, we withdraw the variable and shipping cost from the total price of $21, and that owuld leave a $1 profit per unit, multiplied by 3,400 units that the client wants, the result would be an increase of $3,400 dollars on net income.
