Question

Liz is shipping a package to her friend.the maximum weight of a medium flat-rate box is 20 pounds,including the box which weighs 6 ounces.write and solve an inequality to describe the possible weight ,w, of the contents that Liz will ship to her friend if she must use a medium flat-rate box.

Answer 1

`w+0.375\leq 20` and Liz can ship maximum 19.6 pounds.

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.
`w+0.375\leq 20`

i.e.
`w\leq 20-0.375`

i.e.
`w\leq 19.6`

Thus, Liz can ship maximum 19.6 pounds.
