For this case, the first thing we must do is define the following variables:
x: number of packages of screws
y: number of groups
The relationship between the variables is given by:
![n = (x)/(y)](https://img.qammunity.org/2019/formulas/mathematics/college/scajmwagdjp6dw61abocribxzm6u3js8dt.png)
Substituting values we have:
![n = (2345)/(5)](https://img.qammunity.org/2019/formulas/mathematics/college/raxm5ehzhlfwhtzwxdh27qa72qrip9uone.png)
Finally, dividing both values we have:
![n = 469](https://img.qammunity.org/2019/formulas/mathematics/college/dbf7gd841qvmufigjubbxkhtdudrmw4t06.png)
Answer:
There are 469 packages of screws in each shipping box
