1. In cell M15, create a dsum formula to determine the total sales for PENS for the east Region. Use the criteria range starting in cell W1.

2. With the upper northwest corner starting in cell L20, create a 1 variable data table that will give the TOTAL COST and TOTAL SALE of the binders found in cell H11 and I11. The unit cost has been varied from $1.99 to $3.09 by every $0.10
