Vetkoek recipe questions: 1.4 Calculate oil needed in tablespoons for one batch. 1.5 Calculate yeast needed for 10 large vetkoeks.

$$\text{Oil needed for one batch} = 75 \text{ ml}$$ $$\text{Volume of one tablespoon} = 15 \text{ ml}$$

$$\text{Number of tablespoons} = \frac{75 \text{ ml}}{15 \text{ ml/tablespoon}}$$ $$\text{Number of tablespoons} = 5$$

Nomsa will need 5 full tablespoons of oil.

• 5 full tablespoons

1.5 Calculate the amount of yeast (in grams) Nomsa would need if she decided to only make 10 large vetkoeks.

$$\text{Yeast for 10 vetkoeks} = 0.25 \text{ g/vetkoek} \times 10 \text{ vetkoeks} = 2.5 \text{ g}$$

Nomsa would need 2.5 grams of yeast.

• 2.5 g

1.6 Nomsa wants to make 120 vetkoeks in total. Calculate how many litres of lukewarm water she will need for this order.

One batch makes 40 vetkoeks.

$$\text{Number of batches} = \frac{120 \text{ vetkoeks}}{40 \text{ vetkoeks/batch}} = 3 \text{ batches}$$

$$\text{Total water needed} = 0.5 \text{ L/batch} \times 3 \text{ batches} = 1.5 \text{ L}$$

Nomsa will need 1.5 litres of lukewarm water.

• 1.5 L

1.7.1 Calculate the total time, in minutes, it takes to complete ONE batch.

$$\text{Total time} = \text{Preparation} + \text{First rise} + \text{Shaping} + \text{Frying}$$ $$\text{Total time} = 15 \text{ minutes} + 60 \text{ minutes} + 10 \text{ minutes} + 15 \text{ minutes}$$ $$\text{Total time} = 100 \text{ minutes}$$

It takes 100 minutes to complete one batch.

• 100 minutes

1.7.2 Determine the latest time she should start her preparation to ensure the batch is ready at 11:00.

$$11:00 - 1 \text{ hour } 40 \text{ minutes}$$

Subtracting 1 hour from 11:00 gives 10:00.
Subtracting 40 minutes from 10:00 gives 09:20.
The latest time she should start her preparation is 09:20.

• 09:20
