Ok so most of these stuff are filler items like pasta and potatoes and beans. However you have some cheese and some veggies. How much is your grocery order for the week?
The food and supplies are costing me average $120 a day so I'm making about $155 after costs, does that sound normal?
So how many hours are you working per day to earn the $155 you are left with once your costs are covered? That gives you an hourly rate and from there you can decide whether that’s enough to justify the effort.
Im still trying to understand how you came up with this number. Do you have a breakdown? It sounds way too low. More like you’ll be losing money. Do you need to do the shopping also? Even just making the shopping lists for someone else to do takes time. Have you factored all this in?
