Calculating the Original Price Before VAT

When a product costs R124 including 15% VAT, it's essential to calculate the original price before VAT was added. This can be achieved by using the formula:

Original Price = Total Price / (1 + VAT Percentage)

In this case, the total price is R124, and the VAT percentage is 15%. To calculate the original price, we need to divide the total price by (1 + 0.15).

Step-by-Step Calculation

Convert the VAT percentage to a decimal by dividing by 100: 15% = 0.15
Add 1 to the VAT percentage: 1 + 0.15 = 1.15
Divide the total price by the result: R124 ÷ 1.15 = R108.70

Therefore, the original price before VAT was added is R108.70.

Understanding the Cost of a Dripping Tap

A dripping tap loses 10 ml of water every minute. To understand the cost of this water loss, we need to calculate the total amount of water lost per hour and then convert it to liters.

Step-by-Step Calculation

Calculate the total amount of water lost per hour: 10 ml/minute × 60 minutes = 600 ml/hour
Convert milliliters to liters: 600 ml = 0.6 liters

Calculating the Cost of Water Loss

To calculate the cost of water loss, we need to know the cost of water per liter. Assuming the cost of water is R5 per 1000 liters, we can calculate the cost of water loss as follows:

Step-by-Step Calculation

Calculate the cost of water per liter: R5 ÷ 1000 liters = R0.005 per liter
Multiply the cost of water per liter by the amount of water lost per hour: R0.005 per liter × 0.6 liters = R0.003 per hour

Therefore, the cost of water loss per hour is R0.003.

Calculating the Total Cost of Water Loss per Day

To calculate the total cost of water loss per day, we need to multiply the cost of water loss per hour by the number of hours in a day.

Step-by-Step Calculation

Calculate the number of hours in a day: 24 hours
Multiply the cost of water loss per hour by the number of hours in a day: R0.003 per hour × 24 hours = R0.072 per day

Therefore, the total cost of water loss per day is R0.072.

Conclusion

In conclusion, the original price before VAT was added is R108.70, and the total cost of water loss per day is R0.072. These calculations demonstrate the importance of understanding VAT and calculating original prices, as well as the cost of water loss due to a dripping tap.

Frequently Asked Questions (FAQs) =====================================

Q: What is VAT, and how does it affect the price of goods and services?

A: VAT, or Value-Added Tax, is a type of consumption tax that is levied on the value added to goods and services at each stage of production and distribution. The VAT rate is typically a percentage of the sale price of the goods or services, and it is usually added to the price of the item. For example, if a product costs R100 and the VAT rate is 15%, the total price would be R115.

Q: How do I calculate the original price of a product before VAT was added?

A: To calculate the original price of a product before VAT was added, you can use the following formula:

Original Price = Total Price / (1 + VAT Percentage)

For example, if the total price is R124 and the VAT percentage is 15%, the original price would be:

Original Price = R124 / (1 + 0.15) = R108.70

Q: What is the cost of a dripping tap, and how can I calculate it?

A: The cost of a dripping tap can be calculated by determining the amount of water lost per hour and then converting it to liters. Assuming the cost of water is R5 per 1000 liters, you can calculate the cost of water loss as follows:

Calculate the total amount of water lost per hour: 10 ml/minute × 60 minutes = 600 ml/hour
Convert milliliters to liters: 600 ml = 0.6 liters
Multiply the cost of water per liter by the amount of water lost per hour: R0.005 per liter × 0.6 liters = R0.003 per hour

Q: How can I reduce the cost of water loss due to a dripping tap?

A: To reduce the cost of water loss due to a dripping tap, you can take the following steps:

Fix the tap: Repair or replace the tap to prevent water from leaking.
Use a water-saving device: Install a device that reduces water flow or detects leaks.
Conserve water: Take shorter showers and turn off the tap while brushing your teeth.
Monitor water usage: Keep track of your water usage to identify areas for improvement.

Q: What are some real-world applications of understanding VAT and calculating original prices?

A: Understanding VAT and calculating original prices has various real-world applications, including:

Business: Accurate accounting and financial reporting
Personal Finance: Budgeting and avoiding overspending
Environmental Conservation: Reducing water waste and conserving resources
