Answer
The difference is of $1252\text{ billion dollars}$
Work Step by Step
Consider the given bar graph.
From the image above, the number corresponding to $2007$year are,
Money collected was $2568$ billion dollars
Money spent was$2729$ billion dollars
So, the total difference in amount is,
$\begin{align}
& \text{Diff }=\text{money collected - money spent} \\
& =2568-2729 \\
& =-161
\end{align}$
Thus, the difference is of$-161\,\,\text{billion}\,\text{dollars}$. Since it is negative, the budget is a deficit.
From the image above, the number corresponding to $2009$ year are,
Money collected was $2105$ billion dollars
Money spent was$3518$ billion dollars
So, the total difference in amount is,
$\begin{align}
& \text{Diff }=\text{money collected - money spent} \\
& =2105-3518 \\
& =-1413
\end{align}$
Thus, the difference is of$-\text{1413}\,\,\text{billion}\,\text{dollars}$. Since it is negative, the budget is a deficit.
So, the total difference in amount is,
$\begin{align}
& \text{Diff }=~-161-\left( -1413 \right) \\
& =-161+1413 \\
& =1252
\end{align}$
Thus, difference is of $\text{1252}\,\,\text{billion}\,\text{dollars}$.
