Question

The town collects a sales tax of 10%. Using the new prices, calculate the cost of a 3-square-meter doghouse from Swimmingly Pool Houses company, including tax.

Answer 1

To calculate the total cost of a 3-square-meter doghouse including a 10% sales tax, convert the tax rate to a decimal, multiply it by the pre-tax price to get the sales tax amount, and add this to the original price. If the pre-tax price were $150, the total cost including tax would be $165.

Step-by-step explanation:

To calculate the total cost of a 3-square-meter doghouse from the Swimmingly Pool Houses company, including a 10% sales tax, you must first determine the cost of the doghouse before tax. Assuming that the question provides the pre-tax price, follow these steps to calculate the total cost:

1. Convert the sales tax rate from a percent to a decimal by dividing by 100. For a 10% sales tax, 10 divided by 100 is 0.10.
2. Multiply the pre-tax price of the doghouse by the decimal sales tax rate to find the amount of sales tax. For example, if the pre-tax price is $150, then $150 times 0.10 equals $15 in sales tax.
3. Add the sales tax to the original price to get the total cost. Continuing with the example, $150 plus $15 equals $165.

Therefore, if the pre-tax price of the doghouse were $150, the total cost including sales tax would be $165. Remember to round your sales tax to the nearest cent if necessary, and ensure the final total reflects this rounding.
