Calculate the cost of your sandwich

From Rob Cockerham’s sandwich calculations:

Dijon mustard is to yellow mustard as a Rolls Royce is to your Honda. A 454 gram bottle sells for $6.99, and that is 5 cents per serving.

He adds up exactly how much homemade sandwiches cost based on the amount of ingredients and their correlating prices. The results are revealing: 98 cents for a processed turkey sandwich, 48 1/2 cents for a grilled cheese, and 64 cents for a pb&j.
