Assumptions

• I choose Dolmino's to make the comparison because it was cheaper than PizzaHut.

• I also calculated the leftovers of the ingredients because I could more than pizza with ingredients

• For the cost of the ingredients I reasearched in two shops : Dunnes Stores & Tesco, to make a comparison.

• The prices in the table are the chepeast I could find in the two shops, to make a iqual comparison.

• I choose Tesco to make the comparison because it was cheaper than buying the ingredients at Dunnes.

• When making the pizz I also took in consideration what the cost of the electricity will be to bake it.

• When choosing the size of the pizza in the restaurants I choose a medium size beacause the recipe is for a medium size pizza.

• I'm taking in consideration that will be leftover when making a pizza.

Why did I choose this topic ?

I chose this topic beacause pizza is my favorite food, and I would like to know which is cheaper so I can save money .

Predictions

My prediction is that buying a pizza will be cheaper

Process

Step 6

Step 5

Step 4

Compare the total price of the ingredients and the price of the pizza Pepperoni in the restaurant

Find the price of the pizza Pepperoni

Research pizza restaurants

Process

Step 3

Step 2

Step 1

Research the ingredients for a Pepperoni pizza .

Find out the prices of the pizza Pepperoni Ingredients

Calculate the total price of the pizza ingredients

STEP 1 = Pizza Pepperoni Ingredients

Pizza Toppings

Pizza Dough

• 125 g Pomodoro Tomato Sauce
• 170 g Grated mozzarella Cheese
• 80g /20 Slices of pepperoni
• 2g of Grounded Black Pepper

• 250g of Bread Flour
• 7g of Active Dry Yeast
• 4g of Sugar
• 6g of Table Salt
• 30 ml of Olive oil
• 175 ml of Warm Water

*12 servings (makes one 10-12" pizza)

STEP 2 =Prices for the Pepperoni Pizza Ingredients

For the cost of the ingredients I reasearched in two shops : Dunnes Stores & Tesco, to make a comparison. The prices in the table are the chepeast I could find in the two shops, to make a iqual comparison

STEP 3 =

Calculate the total prices of the Ingredients

Total Price at Dunnes Stores

Total Price at Tesco

VS

TOTAL PRICE = € 29.08

TOTAL PRICE = € 30.41

STEP 4 =

Research Pizza Restaurants

• DOLMINO'S

• PIZZAHUT

STEP 5 =

Find the price of the pizza Pepperoni

DOLMINO'S

• Pepperoni Passion
• SIZE = Medium 11.5"
• TOTAL PRICE = €16.00

PIZZAHUT

• Pepperoni Feast
• SIZE = Medium 12"
• TOTAL PRICE = €16.95

STEP 6 =

Comparing the Prices

MAKING THE PIZZA

TOTAL PRICE = € 29.08

VS

BUYING THE PIZZA

TOTAL PRICE = €16.00

CALCULATING LEFTOVERS

With the leftovers I can make 3 more pizzas, but I would have to buy more Pepperoni & Grated mozzarella cheese. I would have an addicional cost for the electricity because I could bake both pizzas at the same time. Even after making two pizzas, I would still have left overs. So I could use the ingredients for other recipes, for example I could use the suger to make a cake.

IS A MEDIUM PIZZA EQUAL TO TWO SMALL ONES ?

SMALL PIZZA

MEDIUM PIZZA

My conclusion from this investigation was that two small pizza are not equal to a medium pizza. Two small pizzas is equal to 914.6 cm², which is 244.3 cm² bigger than a medium pizza.

Clonclusion

What I could clonclude from investigation is that my prediction was right. Buying a pizza is cheaper than making one

Review

• I did enjoy doing this topic.

• I was glad I choose this topic because it was easy to work with and easy to investigate, since I had a little idea of how much it would cost.

• I think if I got the chance to repeat this investigation I would choose more shops and reataurants to compare the prices.

• With this Investigation I learned the true prices of the ingredients and how much the electricity costs to make a pizza.

• Overall I think I did well in My CBA.
