Answer:
[tex]w+0.375\leq 20[/tex] and Liz can ship maximum 19.6 pounds.
Step-by-step explanation:
Let the possible weight of the medium flat-rate box = w pounds.
It is given that there is a box weighing 6 ounces i.e. 0.375 pounds.
Plus, the maximum weight of the package is 20 pounds.
So, we get,
The inequality representing the situation is,
Weight of medium box + 0.375 pounds ≤ Maximum weight of the package
i.e. [tex]w+0.375\leq 20[/tex]
i.e. [tex]w\leq 20-0.375[/tex]
i.e. [tex]w\leq 19.6[/tex]
Thus, Liz can ship maximum 19.6 pounds.
