Step-by-step explanation:

Let the total packing cost be [tex]p[/tex].

Let the total number of packages to be sold to to break be [tex]n[/tex].

Given that packaging cost for each packet is [tex]0.35[/tex]

So,[tex]p=0.35n[/tex].

Let the total income be [tex]pr[/tex]

Given that income of one packet is [tex]2.5[/tex]

So,[tex]pr=2.5n[/tex]

In addition,there is a fixed cost for the ingredients.

So,[tex]2.5n=0.35n+138[/tex]

[tex]2.15n=138\\n=64.18[/tex]

So,atleast [tex]65[/tex] packets has to be sold inorder to avoid losses.
