4, 5, and 7 are mutually coprime, so you can use the Chinese remainder theorem right away.
We construct a number  such that taking it mod 4, 5, and 7 leaves the desired remainders:
 such that taking it mod 4, 5, and 7 leaves the desired remainders:

- Taken mod 4, the last two terms vanish and we have

so we multiply the first term by 3.
- Taken mod 5, the first and last terms vanish and we have

so we multiply the second term by 2.
- Taken mod 7, the first two terms vanish and we have

so we multiply the last term by 7.
Now,

By the CRT, the system of congruences has a general solution

or all integers  ,
,  , the least (and positive) of which is 27.

Answer:
The weight of box and pocking material  pound
 pound
Step-by-step explanation:
Let the weight of box and packing material 
weight of package  pounds
 pounds
total weight  pound
 pound

Subtract both side by 

Hence weight of box and packing material  pound
 pound
