PART 2
1) What would the recipe look like if it had to serve 10 people ? Show your calculations.
- 10/4 = 2.5

ground beef - 0.5 x 2.5 = 1.25 lb
medium onion, diced - 1 x 2.5 = 2.5
stalk celery finely diced - 1 x 2.5 = 2.5
clove garlic, minced - 1 x 2.5 = 2.5
canned tomatoes, chopped - 14 x 2.5 = 35 oz
can tomato paste - 0.5 x 2.5 = 1.25
parsley - 1 x 2.5 = 2.5 tsp
basil - 1.5 x 2.5 = 3.75 tsp
oregano - 1 x 2.5 = 2.5 tsp
sugar - 1 x 2.5 = 2.5 tsp
Worcestershire Sauce - 0.5 x 2.5 = 1.25 tsp
seasoning salt - 0.5 x 2.5 = 1.25 tsp
bay leaf - 1 x 2.5 = 2.5

2) What would the recipe look like if you had to only serve 1 person ? Show your calculations .
- 10÷1 = 10

ground beef - 1.25 ÷ 10 = 0.125 lb
medium onion, diced - 2.5 ÷ 10 = 0.25
stalk celery finely diced - 2.5 ÷ 10 = 0.25
clove garlic, minced - 2.5 ÷ 10 = 0.25
canned tomatoes, chopped - 35 ÷ 10 = 3.5 oz
can tomato paste - 1.25 ÷ 10 = 0.125
parsley - 2.5 ÷ 10 = 0.25 tsp
basil - 3.75 ÷ 10 = 0.375 tsp
oregano - 2.5 ÷ 10 = 0.25 tsp
sugar - 2.5 ÷ 10 = 0.25 tsp
Worcestershire Sauce - 1.25 ÷ 10 = 0.125 tsp
seasoning salt - 1.25 ÷ 10 = 0.125 tsp
bay leaf - 2.5 ÷ 10 = 0.25
