Final answer:
The sales tax on Mr. Chung's hotel bill of $725 at a rate of 6% is calculated by converting the percentage to a decimal (0.06) and multiplying it by the cost before tax, which results in a sales tax of $43.50.
Step-by-step explanation:
The question asks us to calculate the sales tax for Mr. Chung's hotel bill. The initial cost of his stay before tax was $725, and the sales tax rate is 6%. To find the sales tax amount, we first convert the percentage into a decimal by dividing by 100, which gives us 0.06. Then we multiply this decimal by the total cost to find the tax amount.
Here is the calculation step-by-step:
- Convert the sales tax rate from a percent to a decimal: 6% → 0.06.
- Multiply the decimal by the cost before tax: 0.06 × $725.
- Calculate the sales tax amount: $43.50.
Therefore, the sales tax added to Mr. Chung's hotel bill is $43.50, which corresponds to option a.
