Calculating Sales Tax

The sales tax rate is 5%. To calculate the sales tax, we need to multiply the selling price by the sales tax rate.

Formula: Sales Tax = Selling Price x Sales Tax Rate

For example, if the selling price is $90 and the sales tax rate is 5%, the sales tax would be:

$90 x 0.05 = $4.50

Calculating Total Price

The total price is the sum of the selling price and the sales tax.

Formula: Total Price = Selling Price + Sales Tax

For example, if the selling price is $90 and the sales tax is $4.50, the total price would be:

$90 + $4.50 = $94.50

Calculating Discount

The discount is the difference between the marked price and the selling price.

Formula: Discount = Marked Price - Selling Price

For example, if the marked price is $100 and the selling price is $90, the discount would be:

$100 - $90 = $10

Calculating Discount Percentage

The discount percentage is the ratio of the discount to the marked price.

Formula: Discount Percentage = (Discount / Marked Price) x 100

For example, if the discount is $10 and the marked price is $100, the discount percentage would be:

($10 / $100) x 100 = 10%

Calculating Total Discount

The total discount is the sum of the discount and the sales tax.

Formula: Total Discount = Discount + Sales Tax

For example, if the discount is $10 and the sales tax is $4.50, the total discount would be:

$10 + $4.50 = $14.50

Calculating Net Price

The net price is the total price minus the total discount.

Formula: Net Price = Total Price - Total Discount

For example, if the total price is $94.50 and the total discount is $14.50, the net price would be:

$94.50 - $14.50 = $80.00

Conclusion

Q: What is sales tax?

A: Sales tax is a type of tax that is levied on the sale of goods and services. It is typically a percentage of the selling price of the item.

Q: How is sales tax calculated?

A: Sales tax is calculated by multiplying the selling price of the item by the sales tax rate. For example, if the selling price is $90 and the sales tax rate is 5%, the sales tax would be:

$90 x 0.05 = $4.50

Q: What is the difference between marked price and selling price?

A: The marked price is the price at which an item is listed for sale, while the selling price is the actual price at which the item is sold. The selling price may be higher or lower than the marked price, depending on the discount or promotion being offered.

Q: How is discount calculated?

A: Discount is calculated by subtracting the selling price from the marked price. For example, if the marked price is $100 and the selling price is $90, the discount would be:

$100 - $90 = $10

Q: What is discount percentage?

A: Discount percentage is the ratio of the discount to the marked price. It is calculated by dividing the discount by the marked price and multiplying by 100. For example, if the discount is $10 and the marked price is $100, the discount percentage would be:

($10 / $100) x 100 = 10%

Q: What is total discount?

A: Total discount is the sum of the discount and the sales tax. For example, if the discount is $10 and the sales tax is $4.50, the total discount would be:

$10 + $4.50 = $14.50

Q: What is net price?

A: Net price is the total price minus the total discount. For example, if the total price is $94.50 and the total discount is $14.50, the net price would be:

$94.50 - $14.50 = $80.00
