Jack is making barbecue sauce. He uses 3 cups of ketchup, 1 cup of vinegar and 1 cup of honey. If each burger takes 1/4 cup of sauce and each pulled pork sandwich takes 1/6 cup, how many burgers can Jack make if he makes 18 pulled pork sandwiches?
Thoughts? Step-by-step reasoning:

First find how much barbecue sauce Jack makes by adding the volume of each ingredient: 3 cups + 1 cup + 1 cup = 5 cups. Then multiply the number of pulled pork sandwiches by the amount of sauce per sandwich to find the total amount used: 1 / 6 cup / sandwich * 18 sandwiches = 3 cups. Then subtract this amount from the total amount of sauce Jack has to find how much he uses on the burgers: 5 cups - 3 cups = 2 cups. Then divide this amount by the amount of sauce used per burger to find the number of burgers he can make: 2 cups / 1 / 4 cup / burger = 8 burgers.
Thus, the answer is 8.
