so i am not sure as to the cost. But i was curious and calculated the amount made in a morning. 10 sandwhiches every 10 minutes for 3 hours factoring in 20 minutes for time lost that comes to 200 sandwhiches in a morning. lets see.... lets say the sandwhiches are sold for $5 per and the ingredients cost... hmmm 15 eggs per 10 servings ($0.25 per egg) x 300 = $75, Veggies lets say ($4.00 per 10 servings) x 20 = $80, Ketchup is (2oz per serving at $0.20/oz) x 200 = $80.00, Bread ($0.13 Per slice at 2 per) x 200= $52.00, and Butter Lets say ($5.00 Per 16oz use 2 a day) $10.00. That Equates to a Material Cost of $297 and $1,000 For an Entire Days Sales. So about $3.30 Dollars Return for every dollar spent. Factoring Materials for the next day that Means you are making about $700 a day. Spending about 8 hours a day Gathering and prepping. Which comes to $87.50 Per hours at 40 hours a week (excluding weekends) and $3,000 In Profit per week. So i would say that job is VERY worth it :D I was Curious so i made this..... just in case anyone was wondering. After Reviewing the cost of a serving is about $3.12 as of current price converting Korean Won to USD. Which could come in at $624.00 per day and adjusting to $327.00 profit per day, about $40 per hour. Or about $1,635 a Week.
