Answer: The answer is maximum 19.625 pounds.

Step-by-step explanation:  Given that Liz is shipping a package to her friend with maximum weight of a medium flat-rate box 20 pounds, including the box which weighs 6 ounces.

Let the possible weight of the contents in pounds be 'w' that Liz will ship to her friend if she must use a medium flat-rate box.

Weight of the box = 6 ounces = 6 × 0.0625 pounds = 0.375 pounds.

Therefore, the weight of the contents will be

[tex]w\leq 20-0.375\\\\\Rightarrow w\leq19.625.[/tex]

Thus, Liza can ship the contents weight up to 19.625 ponds.
