A shop sells chicken wraps - Junior Cycle Mathematics - Question 8 - 2019

Combination 2: BBQ Sauce and Tikka Combination 3: Sweet Chilli and Fried

To find the total number of combinations, multiply the number of sauces by the number of chicken types. Since there are 4 sauces and 3 chicken types:

$Total = 4 \times 3 = 12$

To calculate the number of calories in the mayonnaise, subtract the sum of the calories from the wrap, fried chicken, and cheese from the total calories:

$Total - (Calories_{wrap} + Calories_{fried chicken} + Calories_{cheese}) = 600 - (150 + 240 + 130) = 600 - 520 = 80$

So, the calories in the mayonnaise are 80 kcal.

The total number of degrees in any circle is 360°. Therefore, the total degrees in the pie chart is:

$360°$

The angles corresponding to the mayonnaise and cheese can be found by calculating the remaining degrees after accounting for the known angles:

1. For mayonnaise: $(80 \text{ calories}) \rightarrow \frac{80}{600} \times 360 = 48°$

2. For cheese: $(130 \text{ calories}) \rightarrow \frac{130}{600} \times 360 = 78°$

The pie chart can be divided into four sectors:

• Wrap: 90°
• Fried Chicken: 144°
• Cheese: 78°
• Mayonnaise: 48°

Each of these sectors should be labeled accordingly.
