1) Click the Run Query icon in the Design Query toolbar (Figure 223). The results are in
Figure 231.

Notice that not all of the last column label is visible because some of the labels are long.
We can fix this problem by using an alias for many of the fields. The labels are replaced by
their aliases.
2) Add Aliases:
Type in the aliases as they are listed in Figure 232.

3) Run the query again. The results are in Figure 233.

We really do not need the column showing the difference between the FuelID fields from
the table and query, so we will hide it. While it will not be visible, it will still be used in the
calculations.
4) Hide a field that does not need to be seen.
Remove the check in the box of the Visible cell as in Figure 234.

5) Rerun the query (Figure 235).

Step 10: Close, save, and name the query.
My suggestion for a name is Fuel Economy.
There are obviously other calculations that can be made in this query such as cost per distance
traveled and how much of the cost belongs to each of the payments types.
