The graph that best represents the given set of data consists of four line segments, each corresponding to a different range of order totals and their respective shipping costs. We will use open circles (○) for the endpoints that are not included in the range and closed circles (●) for the endpoints that are included.

The first line segment represents orders with a total less than $10.00 and has a constant shipping cost of $4.00. This line segment starts with an open circle at the point ($10.00, $4.00) and extends to the left until the closed cirlce at the point ($0, $0) .

The second line segment represents orders with a total between $10.00 and $19.99 and has a constant shipping cost of $8.00. This line segment starts with a closed circle at the point ($10.00, $8.00) and extends to the right until t...
