How to calculate thie table like this

$$\text{Total (R) for an item} = \text{Quantity} \times \text{Unit Price (R)}$$

2. Calculate the "Grand Total (R)" at the bottom:

$$\text{Grand Total (R)} = \sum (\text{Total (R) for each item})$$

Example:
Let's say you have an item:

• Item: Apples
• Quantity: 2 kg
• Unit Price (R): R15.00/kg

To calculate the "Total (R)" for Apples:

$$2 \text{ kg} \times \text{R}15.00/\text{kg} = \text{R}30.00$$

If you had another item, Oranges:

• Item: Oranges
• Quantity: 3 kg
• Unit Price (R): R10.00/kg

To calculate the "Total (R)" for Oranges:

$$3 \text{ kg} \times \text{R}10.00/\text{kg} = \text{R}30.00$$

Then, to calculate the "Grand Total (R)":

$$\text{R}30.00 (\text{for Apples}) + \text{R}30.00 (\text{for Oranges}) = \text{R}60.00$$
