Q1) what would the recipe be if it served 10 people? show your calculations.
4servings x 2.5=10servings
1/2lb=0.5
0.5 x 2.5=1.25lb ground beef
1 x 2.5= 2.5 medium onion diced
1 x 2.5= 2.5 celery finely sliced
1 x 2.5= 2.5 clove garlic
14 x 2.5= 35 oz can tomatoes chopped
0.5 x 2.5= 1.25 can of tomato paste
1 x 2.5= 2.5 tsp parsley
1.5 x 2.5= 3.75 tsp basil
1 x 2.5= 2.5 tsp oregano
1 x 2.5= 2.5 tsp sugar
0.5 x 2.5= 1.25 tsp worchestershire sauce
0.5 x 2.5= 1.25 tsp seasoning salt
1 x 2.5= 2.5 bay leaves

Q2) what would the recipe be if it was for 1 person? show your calculations.
10servings divided by 10 equals 1serving
1.25 ÷ 10= 0.125 lb ground beef
2.5 ÷ 10= 0.25 medium onion diced
2.5 ÷ 10= 0.25 celery finely sliced
2.5 ÷ 10= 0.25 clove garlic
35 ÷ 10= 3.5 oz can tomatoes chopped
1.25 ÷ 10= 0.125 can of tomato paste
2.5 ÷ 10= 0.25 tsp parsley
3.75 ÷ 10= 0.375 tsp basil
2.5 ÷ 10= 0.25 tsp oregano
2.5 ÷ 10= 0.25 tsp sugar
1.25 ÷ 10= 0.125 tsp worchestershire sauce
1.25 ÷ 10= 0.125 tsp seasoning salt
2.5 ÷ 10= 0.25 bay leaf
