I got the first part of 2281 but how do I get the extra 10% to subtract portion?

Daft is a product of the Digby company. Digby's sales forecast for Daft is 2074 units. Digby wants to have an extra 10% of units on hand above and beyond their forecast in case sales are better than expected. (They would risk the possibility of excess inventory carrying charges rather than risk lost profits on a stock out.) Taking current inventory into account, what will Daft's Production After Adjustment have to be in order to have a 10% reserve of units available for sale?
