Mpho is a Grade 10 learner at Greendale High school. The Grade 10 Mathematical Literacy learners decided to have an end year function. Mpho wants to bake cup-cakes using her grannie's recipe. Below is a list of ingredients needed to make 1 dozen of cup-cakes. Ingredients: 2 cups cake flour ¼ cup sugar te 2 teaspoons baking powder • ½ teaspoon salt 4 ½ cup milk 9 ½ cup oil 2 eggs 1 teaspoon vanilla essence Preparation time: 15 minutes Baking time: 20 minutes NOTE: 1 cup = 250ml 1 teaspoon = 5ml +.3 White sugar = cup 20 7*25071 = 167m! Use the information above to answer questions that follow. 4.1 4.2 Determine the number of cup-cakes that can be made using one batch of the recipe. Convert the amount of oil to ml. (2) (2) 4.3 How many cups of sugar will Mpho need to bake for 48 learners? (3) 4.4 Mpho wants to watch a Mathematical literacy show that goes live at 18:30, by what time should she start making 1 dozen cup-cakes to ensure that she finishes 10 minutes before the show? (4) 4.5 Mpho's oven is NOT designed to use °F (Degrees Fahrenheit). If her grannie's recipe says to sets oven to 356°F. Help her to convert the temperature to °C.

4.1 Number of cupcakes in one batch:
- The recipe makes 1 dozen cupcakes.
- 1 dozen = 12 cupcakes.

So, one batch of the recipe makes 12 cupcakes.

4.2 Conversion of oil to ml:
- Given: ½ cup oil
- 1 cup = 250ml
- Therefore, ½ cup = 250ml / 2 = 125ml

So, the amount of oil in ml is 125ml.

4.3 Cups of sugar needed for 48 learners:
- The recipe makes 12 cupcakes.
- Number of learners: 48
- Each learner will get 1 cupcake.

So, the total number of cupcakes needed is 48.
Now, we need to find out how many cups of sugar are needed for 48 cupcakes.

Given: ¼ cup sugar for 12 cupcakes
For 48 cupcakes: (48 / 12) * ¼ cup = 4 * ¼ cup = 1 cup

So, Mpho will need 1 cup of sugar to bake for 48 learners.

4.4 Time to start baking to finish 10 minutes before the show:
- Given: Preparation time = 15 minutes
- Given: Baking time = 20 minutes
- Given: Show starts at 18:30

Total time needed for baking: Preparation time + Baking time = 15 minutes + 20 minutes = 35 minutes
To finish 10 minutes before the show, Mpho needs to start baking 35 minutes before the show starts.
18:30 - 35 minutes = 17:55

So, Mpho should start making 1 dozen cupcakes at 17:55 to finish 10 minutes before the show.

4.5 Conversion of temperature from °F to °C:
- Given: Temperature in °F = 356°F
- To convert from °F to °C, we use the formula: °C = (°F - 32) / 1.8

Calculating:
°C = (356 - 32) / 1.8
≈ (324) / 1.8
≈ 180

So, the temperature in °C is approximately 180°C.
