1. Why did I Choose this Topic ?

• 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.

Assumptions

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 .

My prediction is that buying a pizza will be cheaper

Predictions

Find the price of the pizza Pepperoni

Process

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

Step 6

Step 5

Research pizza restaurants

Step 4

Find out the prices of the pizza Pepperoni Ingredients

Process

Calculate the total price of the pizza ingredients

Step 3

Step 2

Research the ingredients for a Pepperoni pizza .

Step 1

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

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

Pizza Toppings

• 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

Pizza Dough

STEP 1 = Pizza Pepperoni 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 2 =Prices for the Pepperoni Pizza Ingredients

TOTAL PRICE = € 29.08

Total Price at Tesco

TOTAL PRICE = € 30.41

STEP 3 =

Calculate the total prices of the Ingredients

VS

Total Price at Dunnes Stores

• DOLMINO'S

• PIZZAHUT

Research Pizza Restaurants

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

PIZZAHUT

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

DOLMINO'S

STEP 5 =

Find the price of the pizza Pepperoni

Comparing the Prices

STEP 6 =

TOTAL PRICE = €16.00

VS

BUYING THE PIZZA

TOTAL PRICE = € 29.08

MAKING THE PIZZA

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.

CALCULATING LEFTOVERS

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.

SMALL PIZZA

MEDIUM PIZZA

IS A MEDIUM PIZZA EQUAL TO TWO SMALL ONES ?

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

Clonclusion

• 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.
