The chart above shows year-end values for Darnella's investments. For

Vertical bar charts with more than one data value per vertical bar are notorious traps.

To read vertical bar charts with more than one data value, find the top and bottom boundary lines for the segment that matters.

Then find those lines' corresponding values. The start value for stocks, in other words, is not 0. (If we were asked about cash, the start value WOULD be 0.)

From the legend: stocks are indicated by diagonal stripes.

Total value = Value at top line of striped part minus value at bottom line of striped part

At year's end in 2000, striped part's bottom line hits at $6,000
Top line hits at $9,000
Total value: $(9,000 - 6,000) = $3,000 in 2000

2003: Top line hits at $10,000. Bottom line hits at $5,000
Total value: $(10,000 - 5,000) = $5,000 in 2003

Difference? $(5,000 - 3,000) = $2,000
