Answer 1

To find the total price of the desk including a 5.75% sales tax, multiply the desk's price by the sales tax rate in decimal form and add it to the original price. The total is approximately $126.90.

Step-by-step explanation:

To calculate the total price of the desk including sales tax, follow these steps:

1. First, convert the sales tax rate from a percentage to a decimal by dividing it by 100. So, 5.75% becomes 0.0575.
2. Next, calculate the amount of sales tax by multiplying the price of the desk by the decimal sales tax rate: $120.00 × 0.0575.
3. Then, calculate the amount of sales tax: $120.00 × 0.0575 = $6.90.
4. Finally, add the sales tax to the original price to find the total cost: $120.00 + $6.90 = $126.90.

The total price for the desk, including sales tax, rounds to $126.90, which means the closest answer choice would be b) $126.85.
