The cost of sending an overnight package from Los Angeles to Miami is $26.30 for a package weighing up to but not including 1 pound and $4.00 for each additional pound or portion of a pound. A model for the total cost C (in dollars) of sending the package is С = 26.30 + 4.00[[x]], x > 0, where x is the weight in pounds.

The answer is shown in the pic.

Step-by-step explanation:

The cost model will have a fixed cost of $26.30 for 0 ≤ x ≤ 1 lb and variable cost of $4.00/lb for x > 1.

As seen on the pic, the graph will be that of the greatest integer function that is vertically stretched by a factor 4.00 & shifted 26.30 units upward.
