1) What would the recipe look like if it had to serve 10 people? Show your calculations.
ground beef= 0.5 lbs. 0.5/0.5=1. 1x10=10lbs
onion diced =1. 1/1=1. 1x10=10 onions
celery diced=1. 1/1=1. 1x10=10 celery sticks
garlic cloves=1. 1/1=1. 1x10=10 garlic cloves
tomatoes (can) = 14oz. 14/14=1. 1x10=10 cans of tomatoes
tomato paste = .5 can. 0.5/0.5=1. 1x10=5 cans of tomato paste

2) What would the recipe look like if you had to only serve 1 person? Show your calculations.
