44. You build a line chart based on B1:C15. You then add a trendline to the
chart to predict future fundraising totals.

though the totals for days 10 through 14 are blank, Excel charts
those days as zero. The linear trendline predicts that your fundrais-
ing will go down, with a projected total of just over $2,000.
66. You try the same chart again, but this time you use the NA function
instead of "" in the IF statement in step 3. The formula is shown in
cell H16, and the results are in cell J15. Excel understands that NA
values should not be plotted. The trendline is calculated based on
only the data points available and projects a total just under

running on a computer with 8GB of memory, the function never reports
more than 1MB available.
