Math - recipe conversions and costs

Shane is currently doing an assignment in math that calls on the students to find recipes and convert them for a catering event, then research costs online, figure out the total cost, decide how much to charge per customer, and make a flyer to advertise for it. It's a huge assignment, and we've been practicing at home for a few weeks now, but the work has to be done in class.

Not a lot of structure was given, so, being the template queen that I am, I have developed a table to guide Shane through the conversion process and the costing of the ingredients. Here's a blank template, and an example for an egg salad sandwich. I thought it was pretty simple myself until I ran into a few details snags, then I realized how tricky this can be. For example, you only need 1/2 teaspoon of dill, but it is sold in bags by the gram! How many grams are in a teaspoon? Shane and I googled the question and volume to weight conversions depend entirely on what you are measuring. Shane's teacher said he could ask for help, and he would give him an estimate. Still - not so easy! I have a master's degree in statistics, and I was a little stumped for a while. My empathy is with these kids. I hope these templates that I post do provide some help.
